The writer now quotes from Psalm 102. This whole Psalm is a prayer to Jehovah, though verses 15-23 use the third person to speak of God.
Why does it say ‘thine hands’ when we know that in fact the nearest human speech can get to it is to say that he did it at a word? Yes, it is right: he did it at a word, but it was done with all the care of a craftsmen working with his hands. When a craftsman is working with his hands, why is he spending so much time and trouble, paying so much attention to detail, being so careful to get it right? Because what he is doing is intending to please and to be beautiful and to command our attention and praise and our wonder. That is how God has created the skies – at a word, but as if with his hands to make something extraordinarily instructive and beautiful. That is the power, the goodness, and the kindness of God in fashioning things, and especially for his people.
This is one of about twelve instances in the New Testament where a quotation from the Old Testament, which originally used the word Lord, Jehovah, is ascribed to Jesus Christ. Such passages can be powerfully used against the Jehovah’s Witnesses to show them the error of their position. In this instance, it is good to start with the Psalm and to get their agreement that this is indeed a prayer addressed to Jehovah. We can then move to the Hebrews quote and show that the writer has there applied it to Jesus Christ with the obvious conclusion.
