'Thoroughly' in the Bible

Thus says Yahweh of Armies, "They shall thoroughly glean the remnant of Israel like a vine. Turn again your hand as a grape gatherer into the baskets."

For if you thoroughly amend your ways and your doings; if you thoroughly execute justice between a man and his neighbor;

Their Redeemer is strong; Yahweh of Armies is his name: he will thoroughly plead their cause, that he may give rest to the earth, and disquiet the inhabitants of Babylon.
