(10) Thou hast indeed smitten--i.e., thou hast thoroughly worsted; gained a brilliant victory over Edom. (The "indeed" qualifies "smitten.")

Hath lifted.--Rather, lifteth.

Glory of this, and tarry at home.--Literally, be honoured, and abide in thine own house, i.e., be content with the glory thou hast achieved. Rest on thy laurels, and do not risk them by further enterprises which may not turn out so favourably. So the Vulg. Thenius explains: "Show thy might at home," referring to the LXX. (Comp. 2Samuel 6:20).

For why shouldest thou meddle to thine hurt?--Rather, and why shouldst thou challenge or provoke (literally, attack, Deuteronomy 2:5) disaster?

Verse 10. - Thou hast indeed smitten Edom (see ver. 7, and the comment), and thine heart hath lifted thee up - i.e., made thee proud, exalted thee above measure - glory of this, and tarry at home - i.e., rest content with the glory which thou hast gained in thy Edomite war; make thy boast thereof, but do not affront fresh dangers - for why shouldest thou meddle to thy hurt - literally, why wilt thou meddle with misfortune? - that thou shouldest fall, even thou, and Judah with thee? Joash was as confident of success, if it came to war, as Amaziah. His three victories over Syria (2 Kings 13:25) were, he thought, at least as good evidence of military strength as Amaziah's one victory over Edom.

14:8-14 For some time after the division of the kingdoms, Judah suffered much from the enmity of Israel. After Asa's time, it suffered more by the friendship of Israel, and by the alliance made with them. Now we meet with hostility between them again. How may a humble man smile to hear two proud and scornful men set their wits on work, to vilify and undervalue one another! Unholy success excites pride; pride excites contentions. The effects of pride in others, are insufferable to those who are proud themselves. These are the sources of trouble and sin in private life; but when they arise between princes, they become the misery of their whole kingdoms. Jehoash shows Amaziah the folly of his challenge; Thine heart has lifted thee up. The root of all sin is in the heart, thence it flows. It is not Providence, the event, the occasion, whatever it is, that makes men proud, secure, discontented, or the like, but their own hearts do it.Thou hast indeed smitten Edom, and thine heart hath lifted thee up,.... Swelled him with pride and vanity on account of the victory he had obtained over the Edomites; which pride was at the bottom of his message to him, and that goes before a fall: Proverbs 16:18.

glory of this, and tarry at home; be content with the glory of it, and boast of it at home, but do not swagger abroad, and insult thy neighbours:

for why shouldest thou meddle to thy hurt, that thou shouldest fall, even thou, and Judah with thee? suggesting to him, that he had better be quiet, since it would be to the harm, if not the ruin, of him and his kingdom.
