'Retained' in the Bible

So the people took victuals in their hand, and their trumpets; and he sent all the men of Israel every man unto his tent, but retained the three hundred men: and the camp of Midian was beneath him in the valley.

And his father-in-law, the damsel's father, retained him; and he abode with him three days: so they did eat and drink, and lodged there.

So I was left alone, and saw this great vision, and there remained no strength in me; for my comeliness was turned in me into corruption, and I retained no strength.

whose soever sins ye forgive, they are forgiven unto them; whose soever'sins ye retain, they are retained.
