The "everlasting arms" are Moses’ final-blessing image of YHWH’s eternal sustaining strength: "The eternal God is thy refuge, and underneath are the everlasting arms: and he shall thrust out the enemy from before thee; and shall say, Destroy them" (Deuteronomy 33:27). The arms hold from below — you cannot fall lower than they reach. They are everlasting — they do not weary, do not tire, do not give out. They are the LORD’s — neither the saint’s strength nor any creature’s, but God’s own arm bearing His own people. The doctrine is the basis of the great hymn "Leaning on the Everlasting Arms" (Hoffman/Showalter, 1887). Lean. The arms will not fail under your weight.
Moses' final-blessing image: God's arms hold from below.
Image from Moses' final blessing of Israel before his death (Deut 33:27): "The eternal God is thy refuge, and underneath are the everlasting arms." The Hebrew zeroot olam — arms of eternity — describes God's eternal sustaining strength positioned below the saint, so falling cannot exceed His reach. Anthony Showalter's 1887 hymn "Leaning on the Everlasting Arms" carries the imagery into Christian devotion.
Deuteronomy 33:27 — "The eternal God is thy refuge, and underneath are the everlasting arms: and he shall thrust out the enemy from before thee; and shall say, Destroy them."
Isaiah 40:11 — "He shall feed his flock like a shepherd: he shall gather the lambs with his arm, and carry them in his bosom."
Isaiah 46:4 — "And even to your old age I am he; and even to hoar hairs will I carry you: I have made, I will bear, even I will carry, and will deliver you."
Sentimentalized as soft comfort; the actual image is muscular sustaining-strength positioned below.
"Leaning on the Everlasting Arms" sounds gentle. The Mosaic image is muscular: arms positioned below, ready to catch any fall. The eternal God is below you, holding. You cannot fall lower than He reaches.
Recover the position: His arms are below, not just above. The fall has a floor; the floor is His strength.
