'Guards' in the Bible

Unless Yahweh builds the house, they labor in vain who build it. Unless Yahweh watches over the city, the watchman guards it in vain.

He who guards his mouth guards his soul. One who opens wide his lips comes to ruin.

Righteousness guards the way of integrity, but wickedness overthrows the sinner.

Whoever guards his mouth and his tongue keeps his soul from troubles.

Thorns and snares are in the path of the wicked: whoever guards his soul stays from them.

Your guards are like the locusts, and your officials like the swarms of locusts, which settle on the walls on a cold day, but when the sun appears, they flee away, and their place is not known where they are.
