Adam Clarke on Psalms 89:17

For thou art the glory of their strength - They are strong in faith, and give glory to thee, because they know that their strength cometh from the Lord of hosts.

And in thy favor our horn shall be exalted - Instead of תרום tarum, "shall be exalted," תרים tarim, "thou shalt exalt," is the reading of several MSS.: but תרום tarum, "shall be exalted," is supported by forty-four of Kennicott's MSS., and sixty of De Rossi's, as well as by several ancient editions, with the Septuagint, Syriac, Vulgate, and Arabic Versions. In the enjoyment of the Divine favor they shall grow more wise, more holy, more powerful, and, consequently, more happy.
