'Shut' in the Bible

So the men did so; they took two milking cows and harnessed them to the utility cart, but they shut up their calves in the stall.

Here I am! Testify against me before Yahweh and before his anointed one! Whose ox have I taken? Or whose donkey have I taken? Or whom have I exploited? Whom have I oppressed? Or from whose hand have I taken a bribe, that I may shut my eyes {regarding} him?-then I will restore it to you."

When it was told to Saul that David had gone to Keilah, Saul said, "God {has given him} into my hand, because he has shut himself in by going into a city [with] {two barred gates}.
