We can find the Hebrew word for fruit: H6529 פְּרִי priy (per-ee’) n-m.
The word is constructed by the letters “pey, resh, yod”
In the paleo Hebrew ‘pey’ equals ‘Mouth’
‘resh’ equals the ‘head of a man’
and ‘yod’ equals an ‘arm and closed hand’
This means they will know us by words and teachings, our knowledge of the Word of God and our works.
