Romans 11:18 in the World English Bible
don’t boast over the branches. But if you boast, remember that it is not you who support the root, but the root supports you.
Context
17 And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree;
18 Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
19 Thou wilt say then, The branches were broken off, that I might be graffed in.
