'Freely' in the Bible

Yahweh God commanded the man, saying, "Of every tree of the garden you may freely eat;

How much more, if perhaps the people had eaten freely today of the spoil of their enemies which they found? For now has there been no great slaughter among the Philistines."

and to carry the silver and gold, which the king and his counselors have freely offered to the God of Israel, whose habitation is in Jerusalem,

"I will heal their waywardness. I will love them freely; for my anger is turned away from him.
