Matthew Poole and continuators on 2 Kings 5:19

19 And he said unto him, Go in peace . So he departed from him a little way.

These words may contain an answer: Either, First, To his last Petition, v 18. and so the sense may be this, Be not too solicitous about this matter, Go, and the Peace or Blessing of God go along with thee. So the Prophet both Prays to God to bless and direct him in this and all other things, and intimates that God would do so. Or, Secondly, To the former, v. 17. trouble not thy self about any of our Earth, but go to thy own Land, and I with thee from God, and doubt not but God will give thee peace, i. e. his favour and other blessings, which are oft contained in this word, if thou dost persist in this Religion which thou hast now received. Or rather, this is onely a farewel salutation, wherewith the Prophet dismisseth him without any further answer to his requests, or instruction about his doubt: which he forbore by the motion of Gods Spirit, which sometimes gives and sometimes denies instructions to persons or people, as he thinks fit. See Act. 16. 6, 7. And the Prophet by the Spirits direction might forbear to give him particular answers, partly, because these matters were not of such importance as to concern the Essence or Foundation of Religion: and partly, because he was yet but a Novice, and not able to bear all truths, which was for a time the condition of the Apostles, Ioh. 16. 12. nor fit to be pressed to the practise of the hardest Duties, which Christ himself thought not convenient for his Disciples, Matth. 9. 14, 15, 16, 17. And therefore he at present accepts of his profession of the True, and his renunciation of the false Religion; and of this declaration, that what he did in the Temple of Rimmon should not now be (as he had formerly intended and practised it) a religious action towards the Idol, but onely a civil respect to his Master. And what was necessary for him to know further about the Lawfulness or Sinfulness of that action, the Prophet might take another and a more convenient time to inform him.
