17 The seventy-two returned with joy, saying, “Lord, even the demons are subject to us in your name!” 18 And he said to them, “I saw Satan fall like lightning from heaven. 19 Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you. 20 Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven.”
12 “How you are fallen from heaven,
O Day Star, son of Dawn!
How you are cut down to the ground,
you who laid the nations low!
13 You said in your heart,
‘I will ascend to heaven;
above the stars of God
I will set my throne on high;
I will sit on the mount of assembly
in the far reaches of the north; 
14 I will ascend above the heights of the clouds;
I will make myself like the Most High.’
15 But you are brought down to Sheol,
to the far reaches of the pit.
23 Thus says the Lord: “Let not the wise man boast in his wisdom, let not the mighty man boast in his might, let not the rich man boast in his riches, 24 but let him who boasts boast in this, that he understands and knows me, that I am the Lord who practices steadfast love, justice, and righteousness in the earth. For in these things I delight, declares the Lord.” (ESV)
