'Guarded' in the Bible

Now David had said, "Surely {in vain} I guarded all that this fellow had in the desert. And nothing was missed of all that [was] his, but he returned evil against me in place of good!

For he had commanded the unclean spirit to come out of the man. (For it had seized him many times, and he was bound with chains and shackles [and] was guarded, and breaking the bonds he would be driven by the demon into the deserted places.)

When I was with them, I kept them in your name, which you have given to me, and guarded [them], and none of them has perished except the son of destruction, in order that the scripture would be fulfilled.

he said, "I will give you a hearing whenever your accusers arrive also," giving orders [for] him to be guarded in the praetorium of Herod.

[He] ordered the centurion [for] him to be guarded and to have some freedom, and in no way to prevent any of his own [people] [from] serving him.
