And the nation to whom they shall be in bondage
 At the end of the four hundred years, and which was the Egyptian nation: 
 I will judge, said God;
 that is, condemn and punish them, as he did, by inflicting the ten plagues upon them: 
 and after that they shall come forth;
 out of the land of Egypt, and their hard bondage there; and which was brought about by the judgments executed upon the Egyptians: 
 and serve me in this place;
 in the land of Canaan; though these words are not to be found in ( Genesis 15:13 ) what comes nearest them is in ( Exodus 3:12 ) . "Ye shall serve God upon this mountain"; meaning Mount Horeb, where Moses then was, and from whence the law was afterwards given.
