'Protective' in the Bible

When David arrived at his palace in Jerusalem, the king took the ten mistresses whom he had left behind to keep the palace in order and placed them in a separate house, providing for them under the care of a protective guard. He never visited them again, so they were under care until they died, living as if their husbands had died.

Even though we are slaves, our God has not abandoned us in our slavery. Instead, he has extended gracious love to us in the presence of the kings of Persia, to grant us revival, to set up the Temple of our God, to repair its damage, and to give us a protective wall for Judah and Jerusalem.

His protective scales are his pride, they lie sealed tightly together.

"Now, let me tell you, won't you please, what I'm going to do to my vineyard. "I'm going to take away its protective hedge, and it will be devoured; I'll break down its wall, and it will be trampled.
