Commentary for II Samuel 19:18

וְאֶ֨לֶף אִ֣ישׁ עִמּוֹ֮ מִבִּנְיָמִן֒ וְצִיבָ֗א נַ֚עַר בֵּ֣ית שָׁא֔וּל וַחֲמֵ֨שֶׁת עָשָׂ֥ר בָּנָ֛יו וְעֶשְׂרִ֥ים עֲבָדָ֖יו אִתּ֑וֹ וְצָלְח֥וּ הַיַּרְדֵּ֖ן לִפְנֵ֥י הַמֶּֽלֶךְ׃

And there were a thousand men of Benjamin with him, and Ziba the servant of the house of Saul, and his fifteen sons and his twenty servants with him. And they rushed into the Jordan before the king.
