take ... rest ... consider - I will calmly look on and not interpose, while all seems to promise success to the enemy; when figuratively, “the sun’s heat” and “the night dews” ripen their “harvest”; but “before” it reaches its maturity I will destroy it (Isa 18:5; Ecc 8:11, Ecc 8:12).
like a clear heat - rather, “at the time of the clear (serene) heat” [Maurer].
upon herbs - answering to “harvest” in the parallel clause. Maurer translates, “in the sunlight” (Job 31:26; Job 37:21; Hab 3:4).
like ... dew - rather, “at the time of the dew cloud.” God’s “silence” is mistaken by the ungodly for consent; His delay in taking vengeance for forgetfulness (Psa 50:21); so it shall be before the vengeance which in the last day shall usher in the restoration of the Jews (Isa 34:1-8; Isa 57:11, end of the verse, 2Pe 3:3-10).
