וַיַּעֲמֵ֥ד אֶת־פָּנָ֖יו וַיָּ֣שֶׂם עַד־בֹּ֑שׁ וַיֵּ֖בְךְּ אִ֥ישׁ הָאֱלֹהִֽים׃
上帝的人強忍住面容，竭力自持了許久，終於哭了起來。
Rashi
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.
Rashi
For a long time. Like “בשש [=delay],”7See commentary on 2:17 above. and he could not control himself [any longer] and he wept.
