The Hebrew name Be'alyah combines ba'al (lord, master) with Yah (the LORD), meaning 'YHWH is Lord' or 'the LORD is Master.' It appears in 1 Chronicles 12:5 as one of David's mighty warriors who joined him at Ziklag. Theologically, the name encapsulates the core confession of Israel: YHWH alone holds the title of sovereign Lord over all.
This name witnesses to the exclusive lordship of YHWH. In a culture surrounded by Baal worship, the name Be'alyah subverts the pagan title by asserting that Yah is the true ba'al — the one true Master. David's warriors carried names that proclaimed the reign of God, an echo of the later confession that Jesus is Lord (Greek Kyrios, G2962).
