Wesley(i)
20 Well; they were broken off for unbelief, and thou standest by faith.
21 Be not high-minded, but fear. For if God spared not the natural branches, take heed left he also spare not thee.
22 Behold therefore the goodness and severity of God! Toward them that fell severity; but toward thee goodness, if thou continue in his goodness: else shalt thou also be cut off.
