“Boaz, Booz” From Concise Bible Dictionary:

A wealthy Bethlehemite of the tribe of Judah, who married Ruth the Moabitess and was great grandfather of David (Ruth 2-4; Chron. 2:11-12; Matt. 1:55And Salmon begat Booz of Rachab; and Booz begat Obed of Ruth; and Obed begat Jesse; (Matthew 1:5); Luke 3:3232Which was the son of Jesse, which was the son of Obed, which was the son of Booz, which was the son of Salmon, which was the son of Naasson, (Luke 3:32)). Boaz is a type of Christ who in a future day will raise up the name of the dead in Israel through the returned but desolate remnant.

“Boaz” From Concise Bible Dictionary:

This and JACHIN were the names given to two pillars in the porch of the temple built by Solomon. They are minutely described in 1 Kings 7:15-2215For he cast two pillars of brass, of eighteen cubits high apiece: and a line of twelve cubits did compass either of them about. 16And he made two chapiters of molten brass, to set upon the tops of the pillars: the height of the one chapiter was five cubits, and the height of the other chapiter was five cubits: 17And nets of checker work, and wreaths of chain work, for the chapiters which were upon the top of the pillars; seven for the one chapiter, and seven for the other chapiter. 18And he made the pillars, and two rows round about upon the one network, to cover the chapiters that were upon the top, with pomegranates: and so did he for the other chapiter. 19And the chapiters that were upon the top of the pillars were of lily work in the porch, four cubits. 20And the chapiters upon the two pillars had pomegranates also above, over against the belly which was by the network: and the pomegranates were two hundred in rows round about upon the other chapiter. 21And 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. 22And upon the top of the pillars was lily work: so was the work of the pillars finished. (1 Kings 7:15‑22) and 2 Chronicles 3:15-1715Also he made before the house two pillars of thirty and five cubits high, and the chapiter that was on the top of each of them was five cubits. 16And he made chains, as in the oracle, and put them on the heads of the pillars; and made an hundred pomegranates, and put them on the chains. 17And he reared 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 3:15‑17). It will be observed that in Kings and Jeremiah 52:22And he did that which was evil in the eyes of the Lord, according to all that Jehoiakim had done. (Jeremiah 52:2)1 The height of each pillar is 18 cubits, but in Chronicles their length is said to be 35 cubits. The explanation of this difference is that in Kings the height of each is given, and in Chronicles the length of the pillars, the two together; so that the 17+ cubits, with perhaps a socket, would be the same as the 18 cubits in Kings. JACHIN signifies “He will establish,” and BOAZ, “in Him [is] strength”—implying that the kingdom will be established in strength and in peace, under the administration of Christ: thus the names are typical of the millennium. There appears to be an allusion to these pillars in Revelation 3:1212Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God: and I will write upon him my new name. (Revelation 3:12), the overcomer being made a “pillar” in the temple of God.
