'Till' in the Bible

All the people came to urge David to eat food while it was still day; but David took an oath, saying, “May God do so to me, and more also, if I taste bread or anything else before the sun sets.”

You and your sons and your servants shall cultivate the land for him, and you shall bring in the produce, so that your master’s grandson may have food to eat; but Mephibosheth, your master’s grandson, shall always eat at my table.” Now Ziba had fifteen sons and twenty servants.
