Webster(i)
15 For if the rejection of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
16 For if the first fruit is holy, the lump is also holy: and if the root is holy, so are the branches.
17 And if some of the branches be broken off, and thou, being a wild olive-tree, art ingrafted among them, and with them partakest of the root and fatness of the olive-tree;
18 Boast not against the branches. But if thou boastest, thou bearest not the root, but the root thee.
19 Thou wilt say then, The branches were broken off, that I might be ingrafted.
20 Well; because of unbelief they were broken off, and thou standest by faith. Be not high-minded, but fear:
21 For if God spared not the natural branches, take heed lest he also spare not thee.
22 Behold therefore the goodness and severity of God: on them who fell, severity; but towards thee, goodness, if thou shalt continue in his goodness: otherwise thou also shalt be cut off.
23 And they also, if they abide not still in unbelief, shall be ingrafted: for God is able to ingraft them again.
