Exodus 34:9

And he said, If now I have found grace in thy sight, O Lord, let my Lord, I pray thee, go among us; for it is a stiffnecked people; and pardon our iniquity and our sin, and take us for thine inheritance.

And he said, I pray thee go among us — For thy presence is all to our safety and success.

And pardon our iniquity and our sin — Else we cannot expect thee to go among us.

And take us for thine inheritance — Which thou wilt have a particular eye to, and concern for. These things God had already promised Moses; and yet he prays for them, not as doubting the sincerity of God's grants, but as one solicitous for the ratification of them. But it is a strange plea he urges, for it is a stiff-necked people - God had given this as a reason why he would not go along with them, Exodus 33:3. Yea, saith Moses, the rather go along with us; for the worse they are, the more need they have of thy presence. Moses sees them so stiff-necked, that he has neither patience nor power enough to deal with them; therefore, Lord, do thou go among us; else they will never be kept in awe; thou wilt spare, and bear with them, for thou art God and not man.
