"Jachin and Boaz" were the names given by their craftsman to two large cast-bronze pillars that stood on either side of the entrance to the Temple in Jerusalem (see Temples and Physical and Spiritual Temples) which was built by King Solomon according to God's instructions. They were large, eighteen cubits (about 27 feet) high and twelve cubits (about 18 feet) around (see also Biblical Weights and Measures) and highly ornate, as described in the verses below. The symbolic significance of using those names for the pillars, or of the pillars themselves, is not specified in the Scriptures, however in the original Hebrew of the Old Testament (see also The Older Testament), Jachin (in the Hebrew pronounced yaw-keen) means he will establish, and Boaz (in the Hebrew pronounced boe-az) was the name of the man who was the husband of Ruth, the great-grandfather of King David - the key ancestor of Jesus Christ.
"The capitals upon the tops of the pillars"
The pillars named Jachin and Boaz were crafted by an expert worker of bronze from Tyre, a man named Hiram, whose mother was an Israelite of the tribe of Naphtali (see Children of Jacob), and whose father was a man of Tyre:
"And King Solomon sent and brought Hiram from Tyre. He was the son of a widow of the tribe of Naphtali, and his father was a man of Tyre, a worker in bronze; and he was full of wisdom, understanding, and skill, for making any work in bronze. He came to King Solomon, and did all his work."
"He cast two pillars of bronze. Eighteen cubits was the height of one pillar, and a line of twelve cubits measured its circumference; it was hollow, and its thickness was four fingers; the second pillar was the same. He also made two capitals of molten bronze, to set upon the tops of the pillars; the height of the one capital was five cubits, and the height of the other capital was five cubits."
"Then he made two nets of checker work with wreaths of chain work for the capitals upon the tops of the pillars; a net for the one capital, and a net for the other capital. Likewise he made pomegranates; in two rows round about upon the one network, to cover the capital that was upon the top of the pillar; and he did the same with the other capital. Now the capitals that were upon the tops of the pillars in the vestibule were of lily-work, four cubits. The capitals were upon the two pillars and also above the rounded projection which was beside the network; there were two hundred pomegranates, in two rows round about; and so with the other capital. He set up the pillars at the vestibule of the Temple; he set up the pillar on the south and called its name Jachin; and he set up the pillar on the north and called its name Boaz. And upon the tops of the pillars was lily-work. Thus the work of the pillars was finished." (1 Kings 7:13-22 RSV)
The Temple was completed, after 7 years of work, in the eleventh year of Solomon's reign, approximately 950 BC. The Temple, including the pillars named Jachin and Boaz, lasted until the invading Babylonians (see Why Babylon?) destroyed or looted almost everything (see Raiders Of The Lost Ark) in 587 BC. After standing about 360 years, the pillars of bronze named Jachin and Boaz were carried off to Babylon along with the people of Judah:
"The king of Babylon slew the sons of Zedekiah [see Kings of Israel and Judah and Israelite Dynasties] before his eyes, and also slew all the princes of Judah at Riblah. He put out the eyes of Zedekiah, and bound him in fetters, and the king of Babylon took him to Babylon, and put him in prison till the day of his death."
"In the fifth month [see Bible Calendar and Bible Months], on the tenth day of the month - which was the nineteenth year of King Nebuchadnezzar, king of Babylon - Nebuzaradan the captain of the bodyguard who served the king of Babylon, entered Jerusalem. And he burned the house of The Lord, and the king's house and all the houses of Jerusalem; every great house he burned down. And all the army of the Chaldeans, who were with the captain of the guard, broke down all the walls round about Jerusalem. And Nebuzaradan the captain of the guard carried away captive some of the poorest of the people and the rest of the people who were left in the city and the deserters who had deserted to the king of Babylon, together with the rest of the artisans. But Nebuzaradan the captain of the guard left some of the poorest of the land to be vinedressers and plowmen."
"And the pillars of bronze that were in the House of The Lord [see "My Father's House"], and the stands and the bronze sea that were in the House of The Lord, the Chaldeans broke in pieces, and carried all the bronze to Babylon." (Jeremiah 52:10-17 RSV)
