Romans 11:18 in the King James Version
Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
Context
17 But if some of the branches were broken off, and you, being a wild olive, were grafted in among them and became partaker with them of the root and of the richness of the olive tree,
18 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.
19 You will say then, “Branches were broken off, that I might be grafted in.”
