1. The expectations God had concerning them that they would conduct themselves well, v. 8. When he brought them out of Egypt and took them into covenant with himself he said, "Surely they are my people, I take them as such, and am willing to hope they will approve themselves so, children that will not lie," that will not dissemble with God in their covenantings with him, nor treacherously depart from him by breaking their covenant and starting aside like a broken bow. They said, more than once, All that the Lord shall say unto us we will do and will be obedient; and thereupon he took them to be his peculiar people, saying, Surely they will not lie. God deals fairly and faithfully with them, and therefore expects they should deal so with him. They are children of the covenant (Acts iii. 25), children of those that clave unto the Lord, and therefore it may be hoped that they will tread in the steps of their fathers' constancy. Note, God's people are children that will not lie; for those that will are not his children but the devil's.
