Those who were full have hired themselves out for bread,
but those who were hungry have ceased being hungry.
Yes, the barren has given birth to seven sons,
but she who has many sons withers. Bible

“seven sons.” The word seven is masculine, indicating seven sons. The number seven is used in Hannah’s poetry to refer to a perfect number of sons. She herself had six children, Samuel and five other children (1 Sam. 2:21).
