'Grew' in the Bible

There was a long war between the house of Saul and the house of David; but David grew steadily stronger, while the house of Saul grew weaker and weaker [to the point of being powerless].

But the poor man had nothing but one little ewe lambWhich he had purchased and nourished;And it grew up together with him and his children.It ate his food, drank from his cup, it lay in his arms,And was like a daughter to him.
