Jeremiah suggested two difficulties, the first inexperience, the second timidity. God now removes the first of these. Inexperience is no obstacle where the duty is simple obedience His timidity is removed by the promise given him in the next verse.

Whatsoever I command thee - It is my words and message, not thine own, that thou shalt deliver. I shall teach thee; therefore thy youth and inexperience can be no hinderance.

But the Lord said unto me, say not, I am a child,.... This excuse will not be admitted:

for thou shall go to all that I shall send thee; either to "every place", as the Targum paraphrases; or "to all persons to whom" he should be sent, as the Septuagint and Arabic versions render the words; or "to all things for which" he should send him, as the Syriac and Vulgate Latin versions. The sense is, that he should go everywhere, and to every person, and on every errand and message he should be sent unto and with:

and whatsoever I command thee, thou shall speak; out and openly, and keep back nothing through the fear of men; as follows:

This excuse God holds of no account. As prophet to the nations, Jeremiah was not to make known his own thoughts or human wisdom, but the will and counsel of God which were to be revealed to him. This is signified by the clauses: for to all to whom I send thee, etc. The על belonging to תלך stands for אל, and does not indicate a hostile advance against any one. כל after על is not neuter, but refers to persons, or rather peoples; since to the relative אשׁר in this connection, עליהם is quite a natural completion; cf. Isaiah 8:12, and Ew. 331, c. Only to those men or peoples is he to go to whom God sends him; and to them he is to declare only what God commands him. And so he needs be in no anxiety on this head, that, as a youth, he has no experience in the matter of speaking.

But the LORD said unto me, Say not, I am a child: for thou shalt go to all that I shall send thee, and whatsoever I command thee thou shalt speak.

1:7 Thou shalt speak - Fear not, I will make thee eloquent and courageous.

7. to all that-to all "to whom" [Rosenmuller]. Rather, "to all against whom"; in a hostile sense (compare Jer 1:8, 17, 18, 19) [Maurer]. Such was the perversity of the rulers and people of Judea at that time, that whoever would desire to be a faithful prophet needed to arm himself with an intrepid mind; Jeremiah was naturally timid and sensitive; yet the Spirit moulded him to the necessary degree of courage without taking away his peculiar individuality.

1:1-10 Jeremiah's early call to the work and office of a prophet is stated. He was to be a prophet, not to the Jews only, but to the neighbouring nations. He is still a prophet to the whole world, and it would be well if they would attend to these warnings. The Lord who formed us, knows for what particular services and purposes he intended us. But unless he sanctify us by his new-creating Spirit, we shall neither be fit for his holy service on earth, nor his holy happiness in heaven. It becomes us to have low thoughts of ourselves. Those who are young, should consider that they are so, and not venture beyond their powers. But though a sense of our own weakness and insufficiency should make us go humbly about our work, it should not make us draw back when God calls us. Those who have messages to deliver from God, must not fear the face of man. The Lord, by a sign, gave Jeremiah such a gift as was necessary. God's message should be delivered in his own words. Whatever wordly wise men or politicians may think, the safety of kingdoms is decided according to the purpose and word of God.
