הִקְשִׁ֣יחַ בָּנֶ֣יהָ לְּלֹא־לָ֑הּ לְרִ֖יק יְגִיעָ֣הּ בְּלִי־פָֽחַד׃
Endurécese para con sus hijos, como si no fuesen suyos, No temiendo que su trabajo haya sido en vano:
Rashi on Job
She is hardened She deals harshly with her young ones, [distancing them] from her heart as though they were not hers.
Rashi on Job
her toil is in vain and she is not afraid to lose them.
