'Poor' in the Bible

Wherefore, O king, let my counsel be acceptable unto thee, and break off thy sins by righteousness, and thine iniquities by shewing mercy to the poor; if it may be a lengthening of thy tranquillity.

Then he said to me, Have no fear, Daniel; for from the first day when you gave your heart to getting wisdom and making yourself poor in spirit before your God, your words have come to his ears: and I have come because of your words.
