'Ancestor' in the Bible

Also to Shem, the father of all the children of Eber [including the Hebrews], the older brother of Japheth, children were born.

The neighbor women gave him a name, saying, “A son (grandson) has been born to Naomi.” They named him Obed (worshiper). He is the father of Jesse, the father of David [the ancestor of Jesus Christ].

Obed the father of Jesse, and Jesse the father of David [the king of Israel and the ancestor of Jesus Christ].

For [most certainly] You are our Father, even though Abraham [our ancestor] does not know usAnd Israel does not acknowledge us.You, O Lord, are [still] our Father,Our Redeemer from everlasting is Your name.

We have lived only in tents, and have obeyed and done [everything] according to all that Jonadab our father commanded us.
