Can You Identify This Quote from the Bible?

In my current readthrough of the Bible, I recently came upon this gem of a poem. In my experience, it’s not quoted very often by Christians. But it’s rather encouraging and beautiful, isn’t it?

I’ll write more about this poem next week. For now, let’s test your Bible literacy.

To the first person who comments below with the name of the biblical figure associated with these words (the person who wrote or spoke them), I will give an extra entry into the drawing for a reader’s Bible. In addition, I will give another entry to the first person who can identify the reference for the poem (book and chapter). If one person guesses both correctly, he or she will be given two entries.

Just one caveat: You may not look it up. I want to know if you can guess this from memory. Of course, you could look it up and comment anyway to get the reward. And I’ll never know, but God will.

I’ll confirm if someone gets one of the answers right. That will make it easier for others to guess the second answer correctly.

Here is the poem.

“Agree with God, and be at peace; 
thereby good will come to you. 
Receive instruction from his mouth, 
and lay up his words in your heart. 
If you return to the Almighty you will be built up; 
if you remove injustice far from your tents, 
if you lay gold in the dust, 
and gold of Ophir among the stones of the torrent-bed, 
then the Almighty will be your gold 
and your precious silver. 
For then you will delight yourself in the Almighty 
and lift up your face to God. 
You will make your prayer to him, and he will hear you, 
and you will pay your vows. 
You will decide on a matter, and it will be established for you, 
and light will shine on your ways. 
For when they are humbled you say, ‘It is because of pride’; 
but he saves the lowly. 
He delivers even the one who is not innocent, 
who will be delivered through the cleanness of your hands.”
