'Drained' in the Bible

So they put the oxen to death and their blood was given to the priests to be drained out against the altar; then they put the male sheep to death, draining out their blood against the altar, and they put the lambs to death, draining out their blood against the altar.

And they put the Passover lambs to death, the blood being drained out by the priests when it was given to them, and the Levites did the skinning.
