For so was it charged me by the word of the LORD, saying, {f} Eat no bread, nor drink water, nor turn again by the same way that thou camest.

(f) Seeing he had the express word of God, he should not have declined from it, neither for the persuasion of man nor angel.

Wesley's Notes

13:9 For so, and c. - My refusal of thy favour, is not from any contempt, or hatred of thy person; but in obedience to the just command of my God, who hath forbidden me all father converse or communication with thee. Eat nor drink - In that place, or with that people. Whereby God declares, how detestable they were in God's eyes; because they were vile apostates from the true God, and embraced this idol - worship, against the light of their own consciences, merely to comply with the king's humour and command. Nor turn - That by thy avoiding the way that led thee to Beth - el as execrable, although thou wentest by my special command, thou mightest teach all others, how much they should abhor that way, and all thoughts of going to that place, or to such people, upon any unnecessary occasion.

Matthew Henry's Concise Commentary

13:1-10 In threatening the altar, the prophet threatens the founder and worshippers. Idolatrous worship will not continue, but the word of the Lord will endure for ever. The prediction plainly declared that the family of David would continue, and support true religion, when the ten tribes would not be able to resist them. If God, in justice, harden the hearts of sinners, so that the hand they have stretched out in sin they cannot pull in again by repentance, that is a spiritual judgment, represented by this, and much more dreadful. Jeroboam looked for help, not from his calves, but from God only, from his power, and his favour. The time may come when those that hate the preaching, would be glad of the prayers of faithful ministers. Jeroboam does not desire the prophet to pray that his sin might be pardoned, and his heart changed, but only that his hand might be restored. He seemed affected for the present with both the judgment and the mercy, but the impression wore off. God forbade his messenger to eat or drink in Bethel, to show his detestation of their idolatry and apostacy from God, and to teach us not to have fellowship with the works of darkness. Those have not learned self-denial, who cannot forbear one forbidden meal.
