'Always' in the Bible

David said to him, “Do not be afraid, for I will certainly show you kindness for the sake of your father Jonathan, and will restore to you all the land of your grandfather Saul; and you shall always eat at my table.”

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.
