Charles Ellicott Commentary 2 Chronicles 3:17

"And he set up the pillars before the temple, one on the right hand, and the other on the left; and called the name of that on the right hand Jachin, and the name of that on the left Boaz." — 2 Chronicles 3:17 (ASV)

Before the temple. —Vulgate, in vestibulo templi. So 1 Kings 7:21 states, at the porch of the temple. 1 Kings 7:22 adds, and upon the top of the pillars was lily-work.

Jachin ... Boaz. —See 1 Kings 7:21. “The description of the two brazen pillars,” Reuss says, “much more detailed in 1 Kings 7:15 and following, has become almost unintelligible under the pen of the abbreviator.” This is a strong exaggeration. He also pronounces the word bad-debîr in 2 Chronicles 3:16 “absolutely unintelligible,” and to be considered “foreign to the text.” How little we agree with this hasty decision will be evident from our Note on that verse.
