'Precious' in the Bible

Ephraim is stricken, their root is dried up,They will bear no fruit.Even though they bear children,I will slay the precious ones of their womb.

Though he flourishes among the reeds,An east wind will come,The wind of the Lord coming up from the wilderness;And his fountain will become dryAnd his spring will be dried up;It will plunder his treasury of every precious article.
