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.

guide—a counsellor [Calvin] able to help and advise (compare Ps 118:8, 9; 146:3). The head of your family, to whom all the members of the family would naturally repair in emergencies. Similarly the Hebrew is translated in Jos 22:14 and "chief friends" in Pr 16:28 [Grotius].
her that lieth in thy bosom—thy wife (De 13:6).
