KJV:
When thou passest through the waters, I will be with thee; and through the rivers, they shall not overflow thee: when thou walkest through the fire, thou shalt not be burned; neither shall the flame kindle upon thee.
NASB:
"When you pass through the waters, I will be with you; And through the rivers, they will not overflow you. When you walk through the fire, you will not be scorched, Nor will the flame burn you.
