'Buckler' in the Bible

The LORD is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower.

As for God, his way is perfect: the word of the LORD is tried: he is a buckler to all those that trust in him.

Take hold of shield and buckler, and stand up for mine help.

He shall cover thee with his feathers, and under his wings shalt thou trust: his truth shall be thy shield and buckler.
