'Freely' in the Bible

And Jehovah God commanded the man, saying, Of every tree of the garden thou mayest freely eat:

How much more, if haply the people had eaten freely to-day of the spoil of their enemies which they found? for now hath there been no great slaughter among the Philistines.

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

I will heal their backsliding, I will love them freely; for mine anger is turned away from him.
