'Heavily' in the Bible

He took off their chariot wheels, and they drove them heavily; so that the Egyptians said, "Let's flee from the face of Israel, for Yahweh fights for them against the Egyptians!"

Your wrath lies heavily on me. You have afflicted me with all your waves. Selah.

I was angry with my people, I profaned my inheritance, and gave them into your hand: you showed them no mercy; on the aged you have very heavily laid your yoke.
