Exodus 34:8

And Moses made haste
Perceiving the voice ceased, and the Lord was passing on, lest he should be gone, and he lose the favourable opportunity he had:

and bowed his head toward the earth, and worshipped;
threw himself prostrate upon it, and in the most humble manner put up his requests to God, which are expressed in the following verse; he gladly laid hold on this opportunity to use his interest with God for the people of Israel, and to improve the proclamation of grace and mercy, in the forgiveness of sins, now made; which encouraged his faith and hope to draw nigh with a holy boldness, and use freedom with him, and yet with an awe of his majesty, with reverence and godly fear.
