'Thoroughly' in the Bible

Thus saith Jehovah of hosts, They shall thoroughly glean the remnant of Israel as a vine: turn again thy hand as a grape-gatherer into the baskets.

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

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