'King' in the Bible

“The breaker [the Messiah, who opens the way] shall go up before them [liberating them].They will break out, pass through the gate and go out;So their King goes on before them,The Lord at their head.”

“Now, why do you cry out loudly?Is there no king among you?Has your counselor perished?For agony has gripped you like a woman in childbirth.

“My people, remember nowWhat Balak king of Moab devised [with his evil plan against Israel]And what Balaam the son of Beor answered him [turning the curse into blessing for Israel],[Remember what the Lord did for you] from Shittim to Gilgal,So that you may know the righteous and saving acts [displaying the power] of the Lord.”
