'Strengthen Your Heart' in the Bible

And on the fourth day they arose early in the morning, and he prepared to go; but the girl's father said to his son-in-law, "Strengthen your heart with a morsel of bread, and after that you may go."

And on the fifth day he arose early in the morning to depart; and the girl's father said, "Strengthen your heart, and tarry until the day declines." So they ate, both of them.
