'Half' in the Bible

And Jesus replied [and] said, "A certain man was going down from Jerusalem to Jericho, and fell into the hands of robbers, who both stripped him and beat [him]. [After] inflicting blows on [him], they went away, leaving [him] half dead.

And Zacchaeus stopped [and] said to the Lord, "Behold, half of my possessions, Lord, I am giving to the poor, and if I have extorted anything from anyone, I am paying [it] back four times [as much]!"
