'Pledge' in the Bible

Place, I pray Thee, my pledge with Thee; Who is he that striketh hand with me?

For thou takest a pledge of thy brother for nought, And the garments of the naked Thou dost strip off.

The ass of the fatherless they lead away, They take in pledge the ox of the widow,

They take violently away From the breast the orphan, And on the poor they lay a pledge.
