Study Notes for Numbers 21
Verse 1
king Arad the Canaanite — The king 'dwelt in the south' (negeb), the dry southland of Canaan, where Israel had been beaten back to Hormah after the spies' report (Num 14:45). 'The way of the spies' translates Atharim, a word found only in this verse. He 'took some of them prisoners' (shebi, captives) before Israel answered.
Verse 2
vowed a vow — A vow made to the LORD on condition of his answer, like Jacob's at Bethel (Gen 28:20) and Jephthah's (Judg 11:30). 'Utterly destroy' is charam, to put under the ban and devote to the LORD, so that the cities would be his and not Israel's to keep.
Verse 3
Hormah — The name, Chormah, comes from the verb charam of the vow in v.2 ('utterly destroyed'), so the place carries the ban in its name. It lies where Israel had earlier been routed after the spies' report (Num 14:45; Deut 1:44). Here 'the LORD hearkened to the voice of Israel' and delivered up the Canaanites.
Verse 4
much discouraged — Qatsar, literally 'to be cut short', the verb of 'Is the LORD'S hand waxed short?' (Num 11:23) and kin to the noun in 'anguish of spirit' (Ex 6:9). The route 'to compass the land of Edom' was forced on Israel when 'Edom refused to give Israel passage through his border' (Num 20:21).
Verse 5
light bread — Qeloqel, 'light' or insubstantial, a word found only here; the bread loathed is the manna. The people 'spake against God, and against Moses', the sin Psalm 78:19 recalls: 'they spake against God; they said, Can God furnish a table in the wilderness?'
Verse 6
fiery serpents — Saraph, 'burning', used of a poisonous serpent. The same word names the 'seraphims' of Isa 6:2. The LORD 'sent' them among the people, and Moses recalls 'fiery serpents, and scorpions, and drought' in Deut 8:15. Paul cites the event: 'some of them also tempted, and were destroyed of serpents' (1 Cor 10:9).
Verse 8
set it upon a pole — The Hebrew is nes, a standard raised so that all can see it, rendered 'ensign' in Isa 11:10. The remedy is a saraph in image, set where it can be seen. To 'look' (ra'ah) is the whole requirement, and 'shall live' is promised to 'every one that is bitten'.
Verse 9
serpent of brass — The metal is nechosheth, brass or copper, a likeness in the shape of the serpent. Christ applies the pole to himself: 'as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up' (John 3:14). Centuries later Hezekiah broke it, 'for unto those days the children of Israel did burn incense to it' (2 Kgs 18:4).
Verse 13
the other side of Arnon — Israel pitched beyond the Arnon, 'the border of Moab, between Moab and the Amorites'. Jephthah later recalls that Israel 'came not within the border of Moab' (Judg 11:18), as the LORD had commanded: 'Distress not the Moabites' (Deut 2:9).
Verse 14
the book of the wars of the LORD — A written record quoted by name, and named nowhere else in Scripture; compare the 'book of Jasher' (Josh 10:13). The fragment names 'the Red sea' and 'the brooks of Arnon' as places where the LORD acted, and it is cited just after Arnon is named as the border of Moab (v.13).
Verse 16
Beer — Be'er is a well, and the place is named for it. The word came from the LORD: 'Gather the people together, and I will give them water.' The verb 'give' (nathan) is the one used at the rock, 'it shall give forth his water' (Num 20:8). The well is then dug by 'the princes' and 'the nobles of the people' (v.18).
Verse 17
Spring up, O well — Israel's song at the well recalls the earlier 'Then sang Moses and the children of Israel this song unto the LORD' (Ex 15:1). 'Sing ye unto it' translates anah, which usually means to answer or respond, so the lines may have been sung in answer to one another.
Verse 21
messengers unto Sihon — The request repeats the one made to Edom (Num 20:14–21), and Moses recounts it as 'words of peace' (Deut 2:26). Jephthah quotes the same sending when he answers Ammon: 'And Israel sent messengers unto Sihon king of the Amorites' (Judg 11:19).
Verse 24
from Arnon unto Jabbok — The conquest reached the Jabbok, the river Jacob crossed at the 'ford' (Gen 32:22), and stopped at Ammon, 'for the border of the children of Ammon was strong'. That land the LORD had reserved: 'I will not give thee of the land of the children of Ammon any possession' (Deut 2:19). The victory is praised in Ps 136:19.
Verse 26
Heshbon — The city was Sihon's, but he had taken it from 'the former king of Moab' and 'all his land… even unto Arnon', so Israel took Amorite territory and not Moab's. Jephthah uses this when answering Ammon: Israel 'dwelt in Heshbon and her towns' for three hundred years (Judg 11:26).
Verse 27
they that speak in proverbs — The participle is mashal, the verb behind a proverb, taunt or parable, as in the 'proverb against the king of Babylon' (Isa 14:4). The song vv.27–30 begins 'Come into Heshbon' and goes on to say that 'a fire gone out of Heshbon' consumed 'Ar of Moab' (v.28).
Verse 33
Og the king of Bashan — Israel 'turned and went up by the way of Bashan', and Og came out 'to the battle at Edrei'. Moses retells it nearly word for word in Deut 3:1. Og is described as one 'who remained of the remnant of the giants' (Josh 13:12).
Verse 34
Fear him not — The LORD's words to Moses are repeated in Deut 3:2: 'Fear him not: for I will deliver him, and all his people, and his land, into thy hand.' The defeat of Sihon is the pattern: 'as thou didst unto Sihon'. The result is given in Deut 3:3, 'until none was left to him remaining'.
