Thou wilt say then, the branches were broken off, that I might be grafted in. Romans 11:19
After the cambium layers are matched, they are secured and protected from the elements until the two become one. But thou, O LORD, art a shield for me; my glory, and the lifter up of mine head. Psalm 3:3All exposed pieces are covered with grafting wax to keep out pests, bacteria, and anything harmful to the newly connected branches.
Covered and protected with plastic as well as paper, the joining process is ready to take place without outside interference.
And if some of the branches be broken off, and thou, being a wild olive tree, wert grafted in among them, and with them partakest of the root and fatness of the olive tree; Romans 11:17
