'Pledge' in the Bible

Please lay down a pledge for me with yourself; who [is] he [who] will give security for my hand?

"Indeed, you have required a pledge from your family for nothing, and you have stripped off [the] clothes of [the] naked.

They drive away [the] donkey of orphans; they take [the] widow's ox as a pledge.

"They snatch [the] orphan from [the] breast, and they take a pledge against [the] needy.
