Charles H. Spurgeon on Psalms 132:2

Where the interpreters have translated, "the God of Jacob", it is in the Hebrew, "the mighty in Jacob." Which name is sometimes attributed unto the angels, and sometimes it is also applied to other things wherein are great strength and fortitude; as to a lion, an ox, and such like. But here it is a singular word of faith, signifying that God is the power and strength of his people; for only faith ascribes this unto God. Reason and the flesh do attribute more to riches, and such other worldly helps as man seeth and knoweth. All such carnal helps are very idols, which deceive men, and draw them to perdition; but this is the strength and fortitude of the people, to have God present with them...So the Scripture saith in another place: "Some trust in chariots, and some in horses, but we will remember the name of the Lord." Likewise Paul saith: "Be strong in the Lord, and in the power of his might." For this power is eternal, and deceives not. All other powers are not only deceitful, but they are transitory, and continue but for a moment. —Martin Luther.
