And Jeremiah commanded Baruch, saying, I [am] shut up,.... In prison, according to Jarchi; but this is not likely, for then there would have been no occasion for an order to take him, Jer 36:26. Grotius thinks he was obliged by the king's order to stay at home; possibly he might be restrained by the Spirit of God, or had not freedom in his own mind to go abroad; there might be a restraint, an impulse upon his spirit, by the Spirit of God.
Some think he was under some legal pollution, which made him unfit to go into the temple: for it follows:I cannot go into the house of the Lord: labouring either under some bodily infirmity, or ceremonial defilement, or was forbidden by the king.
