The idea of divine power being granted
to the human king may lie behind two titles applies to the “messianic” figure
in Isaiah 9:5. This person is called both ‘ēl gibbôr, “warrior-god,” and
‘ăbî’ad, “eternal father.” Both of these titles draw on the tradition of
Yahweh’s titles as ‘ēl gibbôr (Isa 10:21) and ‘āb (Deuteronomy
32:6; Jeremiah 3:19, 31:7-9). Finally, ‘ēl gibbôr may be viewed as the heightening
of the royal title gibbôr (Psalm 45:5). (Mark. S. Smith, The Origins
of Biblical Monotheism: Israel’s Polytheistic Background and the Ugaritic Texts
[Oxford: Oxford University Press, 2001], 159)
