A witness, according to Merriam-Webster’s definition, is a person who sees an event take place and could make a statement about it. Ever hear someone ask, “Can I get a witness?” They are asking, “Has anyone experienced something like this?” They want an individual with a similar experience who’s willing to testify as such.
Let the redeemed of the Lord say so, whom he has redeemed from trouble.
Psalm 107:2
While it’s a modern, urban phrase, today’s psalmist may as well have asked, “Can I get a witness?” He begins the psalm with praise. “Oh give thanks to the Lord, for he is good, for his steadfast love endures forever!” (Psalm 107:1) Confirming his declaration, he then says the words of today’s verse…essentially asking for a witness to the greatness of God.
