1 Kings 13:9

For so was it charged [Heb. he, sc . the Lord, charged me ] me by [Heb. in ] the word of the Lord, saying, Fat no bread, nor drinkwater [Participation in food—the "eating salt"—is in the East a token of friendship and affinity; a sign of close communion and fellowship. The prophet's refusal to participate was consequently a practical and forcible disclaimer of all fellowship, a virtual excommunication, a public repudiation of the calf worshippers.

Cf. 1 Corinthians 5:11 ," With such an one, no, not to eat." As Corn. à Lapide, "Ut ipso facto ostenderet, Bethelitas idololatras adeo esse detestabiles, et a Deo quasi excommunicates, ut nullum fidelium cum iis cibi vel potus communionem habere velit"], nor turn again by the same way that thou camest. [ the object of this command was not "simply to test the obedience of the prophet" (Rawlinson), nor yet that no one might "force him to a delay which was irreconcilable with his commission" (Keil), for that was practically executed, but to avoid as far as possible—what, indeed, happened in spite of these precautions—his being traced and followed. Because of this provision, the old prophet ( 1 Corinthians 5:10 ) was reduced to ask, "What way went he?" But the charge, we can hardly doubt,was also designed to serve another purpose, viz; to warn the prophet against doing what he did presently—against returning to Bethel. When he was followed, and when he was told of a revelation commanding his return, he should have remembered, among other things, that it had clearly been part of God's purpose, as evidenced by the explicit instructions given him, that he should not be followed. This alone should have led him to suspect this old prophet of deceit.]
