Matthew Henry on 2 Kings 13:10-19

Jehoash, the king, came to Elisha, to receive his dying counsel and blessing. It may turn much to our spiritual advantage, to attend the sick-beds and death-beds of good men, that we may be encouraged in religion by the living comforts they have from it in a dying hour. Elisha assured the king of his success; yet he must look up to God for direction and strength; must reckon his own hands not enough, but go on, in dependence upon Divine aid. The trembling hands of the dying prophet, as they signified the power of God, gave this arrow more force than the hands of the king in his full strength. By contemning the sign, the king lost the thing signified, to the grief of the dying prophet. It is a trouble to good men, to see those to whom they wish well, forsake their own mercies, and to see them lose advantages against spiritual enemies.
