'Son' in the Bible

In the eighth month, in the second year of Darius, the word of Yahweh came to Zechariah the son of Berechiah, the son of Iddo, the prophet, saying,

On the twenty-fourth day of the eleventh month, which is the month Shebat, in the second year of Darius, the word of Yahweh came to Zechariah the son of Berechiah, the son of Iddo, the prophet, saying,

"Take of them of the captivity, even of Heldai, of Tobijah, and of Jedaiah; and come the same day, and go into the house of Josiah the son of Zephaniah, where they have come from Babylon.

Yes, take silver and gold, and make crowns, and set them on the head of Joshua the son of Jehozadak, the high priest;

The crowns shall be to Helem, and to Tobijah, and to Jedaiah, and to Hen the son of Zephaniah, for a memorial in the temple of Yahweh.

I will pour on the house of David, and on the inhabitants of Jerusalem, the spirit of grace and of supplication; and they will look to me whom they have pierced; and they shall mourn for him, as one mourns for his only son, and will grieve bitterly for him, as one grieves for his firstborn.
