'Cruelly' in the Bible

The Israelites cried out for help to the Lord, because Sisera had nine hundred chariots with iron-rimmed wheels, and he cruelly oppressed the Israelites for twenty years.

Oppressors treat my people cruelly; creditors rule over them. My people's leaders mislead them; they give you confusing directions.

All your allies have abandoned you. They no longer have any concern for you. For I have attacked you like an enemy would. I have chastened you cruelly. For your wickedness is so great and your sin is so much.
