'Yourself' in the Bible

Then Zebah and Zalmunna said, “Rise up yourself, and fall on us; for as the man, so is his strength.” So Gideon arose and killed Zebah and Zalmunna, and took the crescent ornaments which were on their camels’ necks.

Now on the fourth day they got up early in the morning, and he prepared to go; and the girl’s father said to his son-in-law, “Sustain yourself with a piece of bread, and afterward you may go.”

On the fifth day he arose to go early in the morning, and the girl’s father said, “Please sustain yourself, and wait until afternoon”; so both of them ate.
