31:17 She begins 1 her work vigorously,
and she strengthens 2 her arms.
1 tn The first word of the eighth line begins with ח (khet), the eighth letter of the Hebrew alphabet.
2 sn The expression “she makes her arm strong” parallels the first half of the verse and indicates that she gets down to her work with vigor and strength. There may be some indication here of “rolling up the sleeves” to ready the arms for the task, but that is not clear.
