7:1-7 The prophet bemoans himself that he lived among a people ripening apace for ruin, in which many good persons would suffer. Men had no comfort, no satisfaction in their own families or in their nearest relations. Contempt and violation of domestic duties are a sad symptom of universal corruption. Those are never likely to come to good who are undutiful to their parents. The prophet saw no safety or comfort but in looking to the Lord, and waiting on God his salvation. When under trials, we should look continually to our Divine Redeemer, that we may have strength and grace to trust in him, and to be examples to those around us.
4. as a brier—or thorn; pricking with injury all who come in contact with them (2Sa 23:6, 7; Isa 55:13; Eze 2:6).
the day of thy watchmen—the day foretold by thy (true) prophets, as the time of "thy visitation" in wrath [Grotius]. Or, "the day of thy false prophets being punished"; they are specially threatened as being not only blind themselves, but leading others blindfold [Calvin].
now—at the time foretold, "at that time"; the prophet transporting himself into it.
perplexity—(Isa 22:5). They shall not know whither to turn.
