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

(b) Seeing the people are of this nature, the rulers need to call on God that he would always be present with his Spirit.

Wesley's Notes

34:9 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, Ex 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.

Jamieson-Fausset-Brown Bible Commentary

9, 10. he said, If now I have found grace in thy sight, O Lord, let my Lord, I pray thee, go among us-On this proclamation, he, in the overflowing benevolence of s heart, founded an earnest petition for the Divine Presence being continued with the people; and God was pleased to give His favorable answer to Moses' intercession by a renewal of His promise under the form of a covenant, repeating the leading points that formed the conditions of the former national compact.

Matthew Henry's Concise Commentary

34:5-9 The Lord descended by some open token of his presence and manifestation of his glory in a cloud, and thence proclaimed his NAME; that is, the perfections and character which are denoted by the name JEHOVAH. The Lord God is merciful; ready to forgive the sinner, and to relieve the needy. Gracious; kind, and ready to bestow undeserved benefits. Long-suffering; slow to anger, giving time for repentance, only punishing when it is needful. He is abundant in goodness and truth; even sinners receive the riches of his bounty abundantly, though they abuse them. All he reveals is infallible truth, all he promises is in faithfulness. Keeping mercy for thousands; he continually shows mercy to sinners, and has treasures, which cannot be exhausted, to the end of time. Forgiving iniquity, and transgression, and sin; his mercy and goodness reach to the full and free forgiveness of sin. And will by no means clear the guilty; the holiness and justice of God are part of his goodness and love towards all his creatures. In Christ's sufferings, the Divine holiness and justice are fully shown, and the evil of sin is made known. God's forgiving mercy is always attended by his converting, sanctifying grace. None are pardoned but those who repent and forsake the allowed practice of every sin; nor shall any escape, who abuse, neglect, or despise this great salvation. Moses bowed down, and worshipped reverently. Every perfection in the name of God, the believer may plead with Him for the forgiveness of his sins, the making holy of his heart, and the enlargement of the Redeemer's kingdom.
