וַיֵּ֨לֶךְ דָּוִ֧יד וְכָל־יִשְׂרָאֵ֛ל יְרוּשָׁלִַ֖ם הִ֣יא יְב֑וּס וְשָׁם֙ הַיְבוּסִ֔י יֹשְׁבֵ֖י הָאָֽרֶץ׃
און דוד און גאַנץ ישׂראל זײַנען געגאַנגען קײן ירושָלַיִם, דאָס איז יבֿוס; און דאָרטן זײַנען געװען די יבֿוסים, די באַװױנער פֿון לאַנד.
Rashi
And David... went, etc. He went immediately to war when all Israel crowned him, so that Israel should not say [that in] all the wars that David waged in the days of Saul and was victorious it was Saul’s luck, and that he was now afraid to fight. Therefore he immediately went to war.
