Charles Ellicott Commentary Jeremiah 42:7

"And it came to pass after ten days, that the word of Jehovah came unto Jeremiah." — Jeremiah 42:7 (ASV)

After ten days. — The interval is significant, as indicating that the prophet would not give an answer of his own on the spur of the moment, but waited in prayer and meditation until there came into his mind what he could utter as an oracle of God. So Ezekiel waited for seven days among the exiles who lived by the river of Chebar, until the word of the Lord came to him (Ezekiel 3:16). When the hour came, the prophet preached to a multitude whose eagerness to hear him had been intensified by the suspense.
