Redeemed Angels that once disobeyed God were those "Clean beasts" inside Noah's Ark!
God tells Noah:
Genesis 6:7 I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them…
Genesis 6:13 The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.
Genesis 7:2 Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.
Genesis 8:5 And the waters decreased continually until the tenth month: in the tenth month, on the first day of the month, were the tops of the mountains seen…
Genesis 8:13 And it came to pass in the six hundredth and first year, in the first month, the first day of the month, the waters were dried up from off the earth...
I found the same Flood in the Book of Esdras!
Ezra 10:13 But the people are many, and it is a time of much rain, and we are not able to stand without, neither is this a work of one day or two: for we are many that have transgressed in this thing…
Ezra 10:16-17 ...And Ezra the priest, with certain chief of the fathers, after the house of their fathers, and all of them by their names, were separated, and sat down in the first day of the tenth month to examine the matter. And they made an end with all the men that had taken strange wives by the first day of the first month. (same as Genesis chapter 8)
How did it happened?
Genesis 5:32-6:8 And Noah was five hundred years old: and Noah begat Shem, Ham, and Japheth. And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them, That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose. And the Lord said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be a hundred and twenty years. There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown. And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. And it repented the Lord that he had made man on the earth, and it grieved him at his heart. And the Lord said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them. But Noah found grace in the eyes of the Lord.
These celestial sons of priests (Sons of God) are “the beasts” that went with Noah and his family inside the ark. "Of every clean beast thou shalt take to thee by sevens, the male and his female"
Ezra 10:18-44 And among the sons of the priests there were found that had taken strange wives: namely, of the sons of Jeshua the son of Jozadak, and his brethren; Maaseiah, and Eliezer, and Jarib, and Gedaliah. And they gave their hands that they would put away their wives; and being guilty, they offered a ram of the flock for their trespass. And of the sons of Immer; Hanani, and Zebadiah. And of the sons of Harim; Maaseiah, and Elijah, and Shemaiah, and Jehiel, and Uzziah. And of the sons of Pashur; Elioenai, Maaseiah, Ishmael, Nethaneel, Jozabad, and Elasah. Also of the Levites; Jozabad, and Shimei, and Kelaiah, (the same is Kelita,) Pethahiah, Judah, and Eliezer. Of the singers also; Eliashib: and of the porters; Shallum, and Telem, and Uri. Moreover of Israel: of the sons of Parosh; Ramiah, and Jeziah, and Malchiah, and Miamin, and Eleazar, and Malchijah, and Benaiah.And of the sons of Elam; Mattaniah, Zechariah, and Jehiel, and Abdi, and Jeremoth, and Eliah. And of the sons of Zattu; Elioenai, Eliashib, Mattaniah, and Jeremoth, and Zabad, and Aziza. Of the sons also of Bebai; Jehohanan, Hananiah, Zabbai, and Athlai. And of the sons of Bani; Meshullam, Malluch, and Adaiah, Jashub, and Sheal, and Ramoth. And of the sons of Pahathmoab; Adna, and Chelal, Benaiah, Maaseiah, Mattaniah, Bezaleel, and Binnui,and Manasseh. And of the sons of Harim; Eliezer,Ishijah, Malchiah, Shemaiah, Shimeon, Benjamin, Malluch, and Shemariah.Of the sons of Hashum; Mattenai, Mattathah, Zabad, Eliphelet, Jeremai, Manasseh, and Shimei. Of the sons of Bani; Maadai, Amram, and Uel, Benaiah, Bedeiah, Chelluh, Vaniah, Meremoth, Eliashib, Mattaniah, Mattenai, and Jaasau, And Bani, and Binnui, Shimei, And Shelemiah, and Nathan, and Adaiah, Machnadebai, Shashai, Sharai, Azareel, and Shelemiah, Shemariah, Shallum, Amariah, and Joseph. Of the sons of Nebo; Jeiel, Mattithiah, Zabad, Zebina, Jadau, and Joel, Benaiah. All these had taken strange wives: and some of them had wives by whom they had children.
The Bible tells us about all these “beasts”:
Ecclesiastes 3:18 I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.”
Job 18:3 Wherefore are we counted as beasts, and reputed vile in your sight?
2 Peter 2:11-12 Whereas angels, which are greater in power and might, bring not railing accusation against them before the Lord. But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption.
God formed each one of us and gave us his breath of life and we all became living souls. So what about the animals? Also they are living things created by God. According to the majority of knowledgeable people today they think that certainly the animals have a soul. "The soul is the principle of life. Since animals and plants are living things, they have souls, but not in the sense in which human beings have souls. Our souls are rational, theirs aren't and ours are rational because they're spiritual, not material". But the truth is that the Word of God states that only eight souls were saved inside of the Ark and do not say that thousands of souls were saved;
1 Peter 3:20 Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, where in few, that is, eight souls were saved by water.
So what this implies? Please remember what Genesis 6:13 says, for the earth is filled with violence through them; Again i ask, What about those living animals? They do not know any better about being violent if they really are. Or may i rephrase it on what the Bible specifically says: What about those Beasts? Well this Beasts (Angels) that were once called the sons of God did not need to be feeding on oxygen to be alive as a living soul because they were and still celestial spiritual beings on the "face" of the Earth which is that Glory place of this Earth called Heaven.
There were Angels inside Noah's Ark!
