1 Kings 7:21

Thus he set up the pillars at the portico of the temple. The pillar to the south he named Jachin, and the pillar to the north he named Boaz.

And he set up the pillars in the porch of the temple: and he set up the right pillar, and called the name thereof Jachin: and he set up the left pillar, and called the name thereof Boaz.
