'Pledges' in the Bible

Now therefore, I pray thee, give pledges to my master the king of Assyria, and I will give thee two thousand horses, if thou be able on thy part to set riders upon them.

For thou hast taken pledges of thy brother for nought, And stripped the naked of their clothing.

Now therefore, I pray thee, give pledges to my master the king of Assyria, and I will give thee two thousand horses, if thou be able on thy part to set riders upon them.

Shall not all these take up a parable against him, and a taunting proverb against him, and say, Woe to him that increaseth that which is not his! how long? and that ladeth himself with pledges!
