Isaiah 43:2 (BBE) When you go through the waters, I will be with you; and through the rivers, they will not go over you: when you go through the fire, you will not be burned; and the flame will have no power over you.saiah 43:2 (CJB) When you pass through water, I will be with you; when you pass through rivers, they will not overwhelm you; when you walk through fire, you will not be scorched-the flame will not burn you.
The Anthem. Oh, it s hard and dry, when the sun is high. And dust is in your throat, When the rain pours down, near fit to drown, And soaks right through your coat. But the hares of the Long Patrol, my lads, Stouthearts they walk with me, Over hill and plain, and back again, By the shores of the wide blue sea. Through mud and mire to a warm campfire, I ll trek with you, old friend, O er lea and dale, in a roaring gale, Right to our journey s end. Yes, the hares of the Long Patrol, my lads, Love friendship more than gold.
