Run, I pray thee, now to meet her, and say unto her: Is it well with thee? is it well with thy husband? is it well with the child?’ And she answered: ‘It is well.’
Rashi on II Kings
And she said, “[All is] well.” This is an abbreviated verse, for it should have been written, “And he asked her, and she said, ‘We are well.’”
Metzudat David on II Kings
Then he asked her, she said to him all is well, and she didn't want to reveal it to him also.
