Charles H. Spurgeon on Psalms 89:17

In thy favour our horn shall be exalted. A man of lofty bearing is said to carry his horn very high. To him who is proudly interfering with the affairs of another it will be said, "Why show your kombu", "horn", "here?" "See that fellow, what a fine horn he has; he will make the people run." "Truly, my lord, you have a great horn." "Chinnan has lost his money; aye, and his hornship too." "Alas, alas! I am like the deer, whose horns have fallen off." —Joseph Roberts "Oriental Illustrations."

Verse 19 (second clause). —(New Translation) A mighty chief have I supplied with help. Literally, "I have equalized help", that is, I have laid or given sufficient help, "upon a mighty one". The verb denotes "to equalize", or "make one thing equal or equiponderant to another", as a means to the end, or vice versa. —Richard Mant.
