1. I suspect the fault is not in "Jehoiakim" in this verse, but in "Zedekiah" in verse 3—that it was in Jehoiakim's reign Jeremiah warned the Ammonites, etc. And he did the same, as to Judah, when Zedekiah was king; verse 12. But it is a matter of fact to be inquired into.
18. It is deeply interesting to compare this verse with Gen. 20:77Now therefore restore the man his wife; for he is a prophet, and he shall pray for thee, and thou shalt live: and if thou restore her not, know thou that thou shalt surely die, thou, and all that are thine. (Genesis 20:7), and John 15:77If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you. (John 15:7). One sees that being a prophet, i.e., having the communication of the mind of God, places one in, and supposes that intimacy with Him which enables to ask and have of Him, and obtain. It produces and implies, in its nature, that kind of confidence, that claim in grace arising from intimacy, that possession of His mind which enables to intercede. Martha was sure Christ was in this position; she did not know, nor realize His intrinsic living power. And note, the Christian, so far as he values his place in Christ, is in this position, "If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done"; compare John 16:26, 2726At that day ye shall ask in my name: and I say not unto you, that I will pray the Father for you: 27For the Father himself loveth you, because ye have loved me, and have believed that I came out from God. (John 16:26‑27); see also 1 Cor. 2:1616For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ. (1 Corinthians 2:16).
