Charles H. Spurgeon on Psalms 144:15

Whose God is JEHOVAH. A word or name well known to us English, by our translators now often retaining that name in the mention of God in our English Bible, and therefore we shall do well to retain it. Lord was a lower word, in common acceptation, than God. But JEHOVAH is a higher name than either, and more peculiar, incommunicable, and comprehensive. Ex 6:3: "I appeared" (saith the Lord) "unto Abraham, unto Isaac, and unto Jacob, by the name God Almighty, but by my name JEHOVAH was I not known to them."

To have God to be our Jehovah is the insurance of happiness to us. For of many, observe but these two things in the name Jehovah: First, God's absolute independency —that he is of himself omnipotent, Ex 3:14: "And God said, I AM THAT I AM." Secondly, God's faithfulness, that he cannot but be as good as his word, Ex 6:2-4, 6: "And I have also established my covenant with them; wherefore say unto the children of Israel, I am JEHOVAH (so in the Hebrew), and I will bring you out from under the burdens of the Egyptians." So that this name is our security of God's performance. Examine we therefore our bonds, and bills, that is, his promises to us; behold, they are all the promises of Jehovah; they must stand good, for they bear his name; they must reflect his name, and promote both our good and God's grand design. —Nathanael Homes, 1678.

With this prayer of Jehovah's anointed One end the prayers of the Book of Psalms. The remaining six psalms consist exclusively of praise and high Hallelujahs. —Lord Congleton, in "The Psalms: a new Version, with Notes", 1875.
