17 But if some of the branches were broken off, and you, a wild olive shoot, were grafted in their place to share the rich root of the olive tree, 18 do not boast over the branches. If you do boast, remember that it is not you that support the root, but the root that supports you. 19 You will say, “Branches were broken off so that I might be grafted in.” 20 That is true. They were broken off because of their unbelief, but you stand only through faith. So do not become proud, but stand in awe. 21 For if God did not spare the natural branches, perhaps he will not spare you.g 22 Note then the kindness and the severity of God: severity toward those who have fallen, but God’s kindness toward you, provided you continue in his kindness; otherwise you also will be cut off. 23 And even those of Israel,h if they do not persist in unbelief, will be grafted in, for God has the power to graft them in again. 24 For if you have been cut from what is by nature a wild olive tree and grafted, contrary to nature, into a cultivated olive tree, how much more will these natural branches be grafted back into their own olive tree.
