Study Notes for Exodus 17
Verse 2
do ye tempt the LORD — 'Chide' is riv, to contend in dispute, and 'tempt' is nasah, to put to the proof. The two verbs give the place its two names in v.7, Meribah and Massah. Moses' charge is recalled in Deut 6:16: 'Ye shall not tempt the LORD your God, as ye tempted him in Massah.'
Verse 6
the rock in Horeb — The LORD stands on the rock, Moses smites it, and the water comes 'in the sight of the elders of Israel'. Paul says Israel 'drank of that spiritual Rock that followed them: and that Rock was Christ' (1 Cor 10:4). The psalmist recalls it: 'He clave the rocks in the wilderness' (Ps 78:15).
Verse 7
Massah, and Meribah — One place, two names: Massah (the test) and Meribah (the contention), after the verbs of v.2. Massah is named only here and in Deut 6:16; 9:22; 33:8. The question 'Is the LORD among us, or not?' lies behind Ps 95:8, 'Harden not your heart, as in the provocation, and as in the day of temptation in the wilderness.'
Verse 8
Amalek — A grandson of Esau: Timna 'bare to Eliphaz Amalek' (Gen 36:12). Moses later recalls how Amalek 'smote the hindmost of thee, even all that were feeble behind thee… and he feared not God' (Deut 25:18). Balaam calls Amalek 'the first of the nations' (Num 24:20).
Verse 9
Joshua — This is his first mention in Scripture. His name was Oshea until Moses 'called Oshea the son of Nun Jehoshua' (Num 13:16). He leads the men while Moses takes 'the rod of God', the rod he had carried back to Egypt (Ex 4:20). He is later Moses' minister on the mount (Ex 24:13).
Verse 11
held up his hand — 'Prevailed' (gabar, to be strong) is used of both sides, so the battle follows the hand, and Israel is stronger when it is raised and Amalek when it is lowered. Later Scripture speaks of 'lifting up holy hands' in prayer (1 Tim 2:8), and the rod of God (v.9) is in Moses' hand on the hill.
Verse 12
his hands were steady — 'Steady' is emunah, firmness, the word elsewhere rendered 'faith' (Hab 2:4) and 'faithfulness' (Ps 89:1). Aaron and Hur 'stayed up' (tamak, to uphold) his hands, one on each side, until sunset. Hur is named with Aaron again when Moses goes up the mount (Ex 24:14).
Verse 14
Write this for a memorial in a book — This is the first use of the verb 'write' in Scripture. 'Utterly put out' doubles the verb machah, to wipe out; Moses repeats it in Deut 25:19, 'thou shalt blot out the remembrance of Amalek from under heaven', and Saul is sent to carry it out (1 Sam 15:2–3).
Verse 15
Jehovahnissi — Yehovah nissi, 'the LORD is my banner'. Nes is a standard raised as a signal, the word rendered 'banner' in Ps 60:4: 'Thou hast given a banner to them that fear thee.' Moses names an altar rather than the battlefield, and v.16 closes with the LORD's own sworn war against Amalek.
