(Abijah was also known as Abi (2 Kings 18:1-2).) He reigned twenty-nine years (2 Kings 18:2). He is also one of the kings mentioned in the genealogy of Jesus in the Gospel of Matthew. William F. Albright has dated his reign to 715 BCE-687 BCE, while E. R. Thiele offers the dates 716 BCE-687 BCE. Wikipedia
