The Greek phrase for “stand firm” implies stability, firmness, and strong devotion to something. The Corinthians of old and modern Christians are encouraged to remain committed to Christ and devoted to Him. Several metaphors come into play here. One can think of a tree standing firm against a strong wind, soldiers holding down a fort, or a spouse supporting an ailing partner. To stand fast is to be loyal, faithful, devoted, and unmoving.

Joseph invites them to live with him in Egypt, and promises the Israelites that God will bring them out of Egypt back to the Promise Land.
