'Thorough' in the Bible

and it be told thee, and thou hearest of it; then thou shalt make thorough inquiry, and if it be truth and the thing be certain, that this abomination hath been wrought in Israel,

and the judges shall make thorough inquiry; and if the witness be a false witness, and he have testified falsely against his brother,

They said to each other, “Who did this?” After they made a thorough investigation, they said, “Gideon son of Joash did it.”

And {he gave them a thorough beating}, and he went down and stayed in the cleft of the rock of Etam.
