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"
