3. Confidence in Yahweh 140:12-13

David could be confident that God would deliver him because He had promised to help the afflicted and the poor in the Mosaic Law. This salvation would result in the righteous thanking God. They could then continue to live before Him in peace.

This psalm encourages God's people to call on Him in distress when wicked people oppress them. We can have confidence in His promises to vindicate the just in situations such as this. His destruction of the wicked will ultimately glorify His name as well as provide salvation for His own.
