Established. — Two different Hebrew words are so translated in this verse. The first is the same word as that used in 2 Samuel 7:12-13, while the second is translated sure in 1 Samuel 2:35; Isaiah 55:3, and would be better rendered here also made sure.
Before thee. — The LXX. has unnecessarily changed this to before me. The thought is, that David is now made the head of the line in which shall be fulfilled the primeval promise “The seed of the woman shall bruise the serpent’s head.” This was originally given simply to the human race (Genesis 3:15); then restricted to the nation descended from Abraham (Genesis 22:18, &c); then limited to the tribe of Judah (Genesis 49:10, comp. Ezekiel 21:27), and now its fulfilment is promised in the family of David.
