Jacob, the son of Isaac and the grandson of Abraham had children by two wives and two concubines. Among them were twelve identified as the "Twelve Tribes" of Israel. However, the number 12 is complicated by the fact that Joseph's 2 sons, Manasseh and Ephraim, took his place as tribal ancestors, thus giving him the double portion of the firstborn son (Gen. 48:22). This would have brought the number of tribal groups to 13, except that Levi, set apart to serve God, received no land but was given portions of the sacrifices and offerings the others made to the Lord. (In Rev.7, Dan is omitted from the list of tribes that contribute 12,000 preachers each for ministry during the tribulation. This helps to explain why Dan is not represented on the 12 foundations of the Holy City in Rev. 21

The 12 Stones of the Breastplate:
A garment worn over the chest of Israel's high priest. The breastplate was a woven pouch nine inches square, attached by gold chains and rings to his ephod, and armless outer vest. It had 12 jewels set in gold filagree and arranged in three rows across. Each precious stone was engraved with the name of one of Israel's 12 tribes. The high priest wore the breastplate when he performed any of his religious functions. The jewels symbolically represented the whole nation, carried into the presence of God close to the high priest's heart.
No matter whose translation of the word or scripture you read, placement of specific stones will differ as do their individual names. Many stones were named regionally.
