# Abraham was the father of Isaac

"Abraham became the father of Isaac" or "Abraham had a son Isaac" or "Abraham had a son named Isaac." Whichever way you translate "was the father of" here, it would be best to translate it the same way throughout the list of Jesus's ancestors.

# Isaac the father of Jacob, and Jacob the father of 

Here the word "was" is understood. Alternate translation: "Isaac was the father of Jacob, and Jacob was the father of"
