In depth

From the study of Joshua 5:1

Range of meaning

To melt, dissolve, flow away, waste away. Used literally of wax or manna melting in the sun (Exod 16:21; Ps 68:2), and very often in a set phrase about the heart: 'the heart melted', meaning courage dissolved under fear or despair.

Against the English

English versions keep 'melted'. That is accurate, but present-day English uses 'my heart melted' for being touched with affection or pity, which is the opposite of what is meant here.

How it drifted

The modern English idiom ('my heart melted when I saw the puppy') developed into a sentimental sense. The biblical phrase is always about terror or loss of nerve.

Used elsewhere in the period

Deut 1:28 (the spies 'made our hearts melt'); Deut 20:8 (the fearful man sent home 'lest he make his brothers' heart melt'); Josh 2:11 (Rahab: 'our heart melted'); Josh 7:5 (after Ai, ironically, Israel's heart melts); Josh 14:8; Isa 13:7; Ezek 21:7. A closely related verb (namog) in the Song of the Sea (Exod 15:15) predicts that 'all the inhabitants of Canaan melted away'.

From the study of Isaiah 13:7

Range of meaning

To melt or dissolve (wax, Psalm 68:2; manna in the sun, Exodus 16:21). Used figuratively of courage dissolving, almost always with 'heart' as subject.

Against the English

All the major English versions keep 'melt,' which is accurate. The danger is reading it as tenderness (a 'heart melting' with compassion). In Hebrew it always means losing courage.

Used elsewhere in the period

It is the holy-war formula (the language of battles where God himself fights). The Canaanites' hearts 'melted' when they heard what the LORD had done for Israel (Joshua 2:11; 5:1). Fearful soldiers are sent home 'so that his brothers' hearts do not melt like his heart' (Deuteronomy 20:8). Nineveh's fall is 'a heart melting' (Nahum 2:10, Hebrew 2:11). Isaiah 19:1 uses it of Egypt's heart before the LORD.

From the study of Isaiah 10:18

Range of meaning

Masas: melt, dissolve, waste away (wax, Ps 68:2; hearts melting, Deut 20:8; Josh 2:11). Nasas appears only here in this sense. Lexicons (BDB, HALOT) give 'be sick, waste away', perhaps linked to Aramaic/Syriac words for sickness. Another root nasas or the noun nes ('banner, signal pole') lies behind 'standard-bearer'.

Against the English

KJV/WEB: 'as when a standardbearer fainteth'. BSB/most modern: 'as a sickness consumes a man' / 'as a sick man wastes away'.

How it drifted

The KJV followed medieval Jewish interpreters who linked noses to nes, 'banner'. Modern lexicons, reading verse 16's 'wasting disease', prefer sickness.

Used elsewhere in the period

Verse 16 announces razon, 'leanness, wasting', among Assyria's stout men. The ancient translations struggled with the line: the Septuagint has someone fleeing from a burning flame, the Vulgate 'a fugitive from terror'. The rare word was already obscure.

    As smoke is blown away, You will drive them out; as wax melts before the fire, the wicked will perish in the presence of God.

  3. Psalm 97:5 נָ֭מַסּוּ they melt

    The mountains melt like wax at the presence of the LORD, before the Lord of all the earth.

    Here: "They melt" or "they melted." The form describes a complete act, and in a hymn about God appearing it can be read as past (a remembered appearance) or as what always happens when he appears. The same verb is used for hearts "melting" in terror, so it carries a sense of collapse as well as heat.

  4. Psalm 112:10 וְנָמָ֑ס and he will melt away

    Here: To dissolve, run, lose solid form. The 'and' plus perfect form carries on from 'is coming out' in v.3, so it points to the future: 'and the mountains will melt.' Hebrew uses the same verb for courage giving way ('hearts melted', Josh 2:11), so a hint of terror sits under the physical picture.
