'Always' in the Bible

Then David said to him, "Don't be afraid, for {I will certainly show} loyal love to you for the sake of Jonathan your father, and I will restore to you all the lands of Saul your father. And you shall always eat food at my table."

You shall till the land for him, you and your sons and your servants; you shall bring [in the produce] and it shall be food for the son of your master that he may eat. But Mephibosheth the son of your master may always eat food at my table." (Now Ziba had fifteen sons and twenty slaves.)

Then she said, "In former times, {they would always say}, 'By all means, let them inquire in Abel,' and so they settled things.
