Genesis 25:25 New English Translation

²⁵The first came out reddish^[a] all over,^[b] like a hairy^[c] garment, so they named him Esau.^[d]

Genesis 25:25 sn Reddish. The Hebrew word translated “reddish” is אַדְמוֹנִי (ʾadmoni), which forms a wordplay on the Edomites, Esau’s descendants. The writer sees in Esau’s appearance at birth a sign of what was to come. After all, the reader has already been made aware of the “nations” that were being born.
Genesis 25:25 tn Heb “all of him.”
Genesis 25:25 sn Hairy. Here is another wordplay involving the descendants of Esau. The Hebrew word translated “hairy” is שֵׂעָר (seʿar); the Edomites will later live in Mount Seir, perhaps named for its wooded nature.
Genesis 25:25 tn Heb “And they called his name Esau.” The name “Esau” (עֵשָׂו, ʿesav) is not etymologically related to שֵׂעָר (seʿar), but it draws on some of the sounds.
