Behold, you are about to lie down with your fathers. Then this people will rise and whore after the foreign gods among them in the land that they are entering, and they will forsake me and break my covenant that I have made with them. Then my anger will be kindled against them in that day, and I will forsake them and hide my face from them, so that they will say in that day, 'Have not these evils come upon us because our God is not among us?' And I will surely hide my face in that day because of all the evil that they have done, because they have turned to other gods. (Deuteronomy 31:16-18)
'Now therefore write this song and teach it to the people of Israel. Put it in their mouths, that this song may be a witness for me against the people of Israel. For when I have brought them into the land flowing with milk and honey, which I swore to give to their fathers, and they have eaten and are full and grown fat, they will turn to other gods and serve them, and despise me and break my covenant. And when many evils and troubles have come upon them, this song shall confront them as a witness (for it will live unforgotten in the mouths of their offspring). For I know what they are inclined to do even today, before I have brought them into the land that I swore to give.' So Moses wrote this song the same day and taught it to the people of Israel. (Deuteronomy 31:19-22)
See now that I, even I, am he, and there is no god beside me; I kill and I make alive; I wound and I heal; and there is none that can deliver out of my hand. ... Rejoice with him, O heavens; bow down to him, all gods, for he avenges the blood of his children and takes vengeance on his adversaries. He repays those who hate him and cleanses his people's land. (Deuteronomy 32:39,43)
There is no shadow of turning with Thee
Thou changest not, Thy compassions they fail not
As Thou hast been, Thou forever wilt be.
