Translation:

3. O ye that are sprung from those whom We carried (in the Ark) with Noah! verily he was a devotee most grateful.

Notes (Tafseer)

2172. After the Deluge of the time of Noah the only descendants of Noah were those who were saved in the Ark with him. They had special reason to celebrate the praises of Allah. But they relapsed into idolatry, sin, and abominations. They are reminded of the true and sincere devotion of Noah himself, as contrasted with the unworthiness of Noah's descendants, especially the Children of Israel.
