'Alien' in the Bible

extinguished the power of [raging] fire, escaped the edge of the sword, out of weakness were made strong, became mighty and unbeatable in battle, putting enemy forces to flight.

Do not be carried away by diverse and strange teachings; for it is good for the heart to be established and strengthened by grace and not by foods [rules of diet and ritualistic meals], which bring no benefit or spiritual growth to those who observe them.
