'Ancestor' in the Bible

The LORD was with Jehoshaphat because he followed the example set during his ancestor David's preliminary years by not pursuing the Baals.

Then a letter came to Jehoram from Elijah the prophet, saying:This is what Yahweh, the God of your ancestor David says: “Because you have not walked in the ways of your father Jehoshaphat or in the ways of Asa king of Judah

"This is what the LORD God of your ancestor David says: "You haven't lived like your father Jehoshaphat and like King Asa of Judah. Instead, you have lived like the kings of Israel by causing Judah and the inhabitants of Jerusalem to commit cultic sexual immorality just like Ahab's dynasty did! And you've killed your brothers who were better than you your own father's dynasty!

Ahaz was 20 years old when he began to reign, and he reigned 16 years in Jerusalem, but he did not practice what the LORD considered to be right, as his ancestor David had done.

He did what was right in the Lord’s sight just as his ancestor David had done.

He did what was right in the Lord’s sight and walked in the ways of his ancestor David; he did not turn aside to the right or the left.

In the eighth year of his reign, while he was still a youth, Josiah began to seek the God of his ancestor David, and in the twelfth year he began to cleanse Judah and Jerusalem of the high places, the Asherah poles, the carved images, and the cast images.
