'Off' in the Bible

Then Hanun took the servants of David, and he shaved off half of their beards and cut their garments off in the middle up to their buttocks, then sent them away.

When he shaved his head, it would happen {every year}, which he did because [it was] heavy on him, he would shave it off and weigh the hair of his head: two hundred shekels {by the king's weight}.

Then Abishai the son of Zeruiah said to the king, "Why should this dead dog curse my lord the king? Please let me go over and take off his head."

Then Joab said to the Cushite, "Go, tell the king what you have seen"; then the Cushite bowed down to Joab and ran [off].
