Psalm 127:3 New English Translation

³Yes,^[a] sons^[b] are a gift from the Lord;
the fruit of the womb is a reward.

Psalm 127:3 tn or “look.”
Psalm 127:3 tn Some prefer to translate this term with the gender neutral “children,” but “sons” are plainly in view here, as the following verses make clear. Daughters are certainly wonderful additions to a family, but in ancient Israelite culture sons were the “arrows” that gave a man security in his old age, for they could defend the family interests at the city gate, where the legal and economic issues of the community were settled.
