If the part of the dough offered as firstfruits is holy, then the whole batch is holy; if the root is holy, so are the branches.
NIV
Now if the first handful of dough offered as the firstfruits [Abraham and the patriarchs] is consecrated (holy), so is the whole mass [the nation of Israel]; and if the root [Abraham] is consecrated (holy), so are the branches. [Num. 15:19-21.]AMP
For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.
KJV
