פירוש על מלכים ב 8:11

He [Elisha] kept his face emotionless. [He held in] his expression of grief, for he wanted to cry; he held it in, so that he would not cry in front of Chazoeil. He made a concentrated effort to stand and control himself.

For a long time. Like “בשש [=delay],”⁷See commentary on 2:17 above. and he could not control himself [any longer] and he wept.
