Charles Ellicott Commentary 2 Kings 4:27

"And when she came to the man of God to the hill, she caught hold of his feet. And Gehazi came near to thrust her away; but the man of God said, Let her alone: for her soul is vexed within her; and Jehovah hath hid it from me, and hath not told me." — 2 Kings 4:27 (ASV)

To the hill. —Probably to the summit.

She caught him by the feet. — She laid hold of (clasped) his feet. Assuming the posture of a humble and urgent suppliant, and no doubt pouring out a flood of passionate entreaties for help.

But (and) Gehazi came near to thrust her away. —He thought her vehemence a trespass upon the dignity of his master. (John 4:27.)

The Lord hath hid it from me. —Supernatural knowledge of every event was not a characteristic of the gift of prophecy. (Compare to 2 Samuel 7:3 and following for a somewhat similar case of ignorance on the part of a prophet.)
