'Wantonly' in the Bible

But if a man act wantonly toward his neighbour, and slay him with guile, thou shalt take him from mine altar, that he may die.

Why should you harden your hearts like [the] Egyptians and Pharaoh hardened their heart? Is it not just like when he dealt with them wantonly so that they sent them away and they left?

For Jehovah brought Judah low because of Ahaz king of Israel; for he had dealt wantonly in Judah, and trespassed sore against Jehovah.

Then those of you who escape will remember Me among the nations to which they will be exiled, how I have been broken by their lewdness and their adulterous hearts which have turned away from Me, and by their eyes which lust after their idols; and they will loathe themselves for the evils which they have committed, for all their repulsive acts.
