'Half' in the Bible

Jesus took up the question and said: “A man was going down from Jerusalem to Jericho and fell into the hands of robbers. They stripped him, beat him up, and fled, leaving him half dead.

But Zacchaeus stood there and said to the Lord, “Look, I’ll give half of my possessions to the poor, Lord! And if I have extorted anything from anyone, I’ll pay back four times as much!”
