Charles Ellicott Commentary Exodus 34:8

"And Moses made haste, and bowed his head toward the earth, and worshipped." — Exodus 34:8 (ASV)

Moses made haste, and bowed his head. —As the Divine glory passed before him, Moses bowed his head in adoration, worshipping God, and not daring to look until the glory had gone by. It is thus seen that with his ardent desire to look into the things of God he combined the highest and deepest reverence.
