Genesis 30:4-6

Amplified Bible

⁴ So she gave him Bilhah her maid as a [^[a]secondary] wife, and Jacob went in to her. ⁵ Bilhah conceived and gave birth to a son for Jacob. ⁶ Then Rachel said, “God has judged and vindicated me, and has heard my plea and has given me a son [through my maid].” So she named him Dan (He judged).
