Being grieved - The word thus translated occurs in only one other place in the New Testament Acts 16:18. It implies more than simple sorrow; it was a mingled emotion of indignation and anger. They did not grieve because they thought it a public calamity, but because it interfered with their authority and opposed their doctrine. It means that it was painful to them, or they could not bear it. It is often the case that bigots, and people in authority, have this kind of grief, at the zeal of people in spreading the truth, and thus undermining their influence and authority.
1 Kings 13 Living Bible (TLB)
As Jeroboam approached the altar to burn incense to the golden calf idol, a prophet of the Lord from Judah walked up to him.
2 Then, at the Lord’s command, the prophet shouted, “O altar, the Lord says that a child named Josiah shall be born into the family line of David, and he shall sacrifice upon you the priests from the shrines on the hills who come here to burn incense; and men’s bones shall be burned upon you.”
3 Then he gave this proof that his message was from the Lord: “This altar will split apart, and the ashes on it will spill to the ground.”
