6:12 Shall horses {n} run upon the rock? will [one] plow [there] with oxen? for ye have turned judgment into gall, and the fruit of righteousness into {o} hemlock:
(n) He compares them to barren rocks, upon which it is in vain to bestow labour: showing that God's benefits can have no place among them.
(o) Read Am 5:7.
6:12 Shall horses - If prophets exhort or advise, it does no more good than if you would run your horses upon the precipices of rocks.
6:8-14 How dreadful, how miserable, is the case of those whose eternal ruin the Lord himself has sworn; for he can execute his purpose, and none can alter it! Those hearts are wretchedly hardened that will not be brought to mention God's name, and to worship him, when the hand of God is gone out against them, when sickness and death are in their families. Those that will not be tilled as fields, shall be abandoned as rocks. When our services of God are soured with sin, his providences will justly be made bitter to us. Men should take warning not to harden their hearts, for those who walk in pride, God will destroy.
