1  God has taken his place in the divine council;
    in the midst of the gods he holds judgment:

2 “How long will you judge unjustly
    and show partiality to the wicked? 

3  "Give justice to the weak and the fatherless;
    maintain the right of the afflicted and the destitute!

4  "Rescue the weak and the needy;
    deliver them from the hand of the wicked.”

5  "They have neither knowledge nor understanding,
    they walk about in darkness;
    all the foundations of the earth are shaken.

6  I said, “You are gods,
    sons of the Most High, all of you;

7  nevertheless, like men you shall die,
    and fall like any prince.”

8  Arise, O God, judge the earth;
    for you shall inherit all the nations!

5  Let the heavens praise your wonders, O Lord,
    your faithfulness in the assembly of the holy ones!

6  For who in the skies can be compared to the Lord?
    Who among the heavenly beings is like the Lord,

7  a God greatly to be feared in the council of the holy ones,
    and awesome above all who are around him?

8  O Lord God of hosts,
    who is mighty as you are, O Lord,
    with your faithfulness all around you?

When man began to multiply on the face of the land and daughters were born to them, 2 the sons of God saw that the daughters of man were attractive. And they took as their wives any they chose. 3 Then the Lord said, “My Spirit shall not abide in[a] man forever, for he is flesh: his days shall be 120 years.” 

4 The Nephilim[b] were on the earth in those days, and also afterward, when the sons of God came in to the daughters of man and they bore children to them. These were the mighty men who were of old, the men of renown.

5 The Lord saw that the wickedness of man was great in the earth, and that every intention of the thoughts of his heart was only evil continually. 6 And the Lord regretted that he had made man on the earth, and it grieved him to his heart. 7 So the Lord said, “I will blot out man whom I have created from the face of the land, man and animals and creeping things and birds of the heavens, for I am sorry that I have made them.” 8 But Noah found favor in the eyes of the Lord.

Genesis 11 - The Tower of Babel

Now the whole earth had one language and the same words. 2 And as people migrated from the east, they found a plain in the land of Shinar and settled there. 3 And they said to one another, “Come, let us make bricks, and burn them thoroughly.” And they had brick for stone, and bitumen for mortar. 4 Then they said, “Come, let us build ourselves a city and a tower with its top in the heavens, and let us make a name for ourselves, lest we be dispersed over the face of the whole earth.” 5 And the Lord came down to see the city and the tower, which the children of man had built. 6 And the Lord said, “Behold, they are one people, and they have all one language, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them. 7 Come, let us go down and there confuse their language, so that they may not understand one another's speech.” 8 So the Lord dispersed them from there over the face of all the earth, and they left off building the city. 9 Therefore its name was called Babel, because there the Lord confused[a] the language of all the earth. And from there the Lord dispersed them over the face of all the earth.

8  When the Most High gave to the nations their inheritance,
    when he divided mankind,
    he fixed the borders of the peoples
    according to the number of the sons of God.

9  But the Lord's portion is his people,
    Jacob his allotted heritage.
