God hath spoken once - God has once addressed his people in giving the law on Mount Sinai. The Chaldee translates the whole passage thus: "God hath spoken one law, and twice have we heard this from the mouth of Moses the great scribe, that strength is before God: and it becomes thee, O God, to show mercy to the righteous; for thou renderest to man according to his works."
Twice have I heard this - Except some of the ancient Versions, almost every version, translation, and commentary has missed the sense and meaning of this verse. I shall set down the text: שמעתי זו שתים אלהים דבר אחת achath dibber Elohim ; shetayim zu shamati ; of which the true version is this: Once hath God spoken; these two things have I heard. Now what are the two things he had heard?
These, then, are the two grand truths that the law, yea, the whole revelation of God, declares through every page. He is the Almighty; he is the most merciful; and hence the inference: The powerful, just, and holy God, the most merciful and compassionate Lord, will by and by judge the world, and will render to man according to his works. How this beautiful meaning should have been unseen by almost every interpreter, is hard to say: these verses contain one of the most instructive truths in the Bible.
God hath spoken once; twice have I heard this - This repetition, or this declaration that he had heard the thing repeated, is designed to give emphasis to what was said, or to call attention to it as particularly worthy of notice. See the notes at Job 33:14. Compare Job 40:5. The sentiment here is particularly important, or is deserving of special attention, because, as the psalmist had shown, all other resources fail, and confidence is to be placed in nothing else for that which man so much needs; neither in people, whether of low degree or high Psalm 62:9; not in oppressive acts - acts of mere power; not in plunder; not in wealth, however acquired, Psalm 62:10.
That power belongeth unto God - Margin, strength. The idea is, that the strength which man needs - the ability to defend and to save him - is to be found in God. All else may fail, but the power of God will not fail. The result of all, therefore, should be to lead us to put our trust in God alone.
