Robertson's Word Pictures (NT)
Harden not (mh sklhrunhte). Prohibition with mh and first aorist (ingressive) active subjunctive of sklhrunw, late verb from sklhrov (dried up, stiff, hard) as in Acts 19:9; Romans 9:18.
As in the provocation (wv hn tw parapikrasmw). Late compound from parapikrainw, late verb to embitter (para, pikrov), found only in LXX and here and verse Hebrews 3:15. It means embitterment, exasperation. For the simple verb pikrainw, to make bitter, see Colossians 3:19. The reference is to Meribah (Exodus 17:1-7).
Like as in the day (kata thn hmeran). "According to the day" as in Acts 12:1; Acts 19:23.
Of the temptation (tou peirasmou). The reference is to Massah which took place at Rephidim.
