'Sons' in the Bible

Yet the number of the sons of IsraelShall be like the sand of the sea,Which cannot be measured or numbered;And in the placeWhere it is said to them,“You are not My people,”It will be said to them,“You are the sons of the living God.”

They sacrifice on the tops of the mountainsAnd burn incense on the hills,Under oaks, poplars, and terebinths,Because the shade is pleasant there.Therefore your daughters play the prostituteAnd your brides commit adultery.

O Israel, you have [willfully] sinned since the days of Gibeah;There they (Israel) stand!Will not the battle against the sons of wickedness overtake them at Gibeah?

They will walk after the Lord [in obedience and worship],Who will roar like a lion;He will roar [summoning them]And His sons will come trembling from the west.
