Literally, “have an appointment.” Just as two people do not walk together unless they have a common purpose in view, so the Lord indicates that the special relationship He held to Israel (v. 2) cannot continue so long as Israel clings to her iniquities. The LXX expressively renders this verse, “Shall two walk together at all, if they do not know one another?” To “walk together” with God means, not an occasional act, but a continuing habit that issues from an established relation. It means a companionship based upon a mutual harmony of mind and spirit. Two people must go in the same direction if they are to walk “together.”

 See on ch. 2:4. This question strikes the keynote of the first of the three messages (see on ch. 3:1).
