'Thick' in the Bible

Then Solomon said, "Yahweh has said that [he] would dwell in the very thick cloud.

As the king [was] passing by, he called to the king and said, "Your servant went out in the thick of the battle, and suddenly a man turned and brought a man to me and said, 'Guard this man. If by any means he should be missed, it will be your life in his place, or you shall pay a talent of silver.'
