וַיֵּ֣לֶךְ מִשָּׁ֔ם אֶל־יוֹשְׁבֵ֖י דְּבִ֑יר וְשֵׁם־דְּבִ֥יר לְפָנִ֖ים קִרְיַת־סֵֽפֶר׃
他從那裡出發，去攻打底璧的居民；底璧從前名叫基列西弗。

And Hushai the Archite - Heb. קִרְיַת סֵפֶר (Jos. 15:15, Jud. 1:11) is translated by the Targum as קִרְיְתָא דְּאַרְכֵי. In Midrash Rabbah we find that when David sinned with Bathsheba, he asked Hushai the Archite whether, if he would repent, the Holy One, blessed be He, would accept his repentance to grant him an extension for his sin, and he said, “Yes.” the king’s companion His best man (Jud. 14: 20): “to his companion (לְמֵרֵעֵהוּ), who had accompanied (רֵעָה) him,” written regarding Samson; it is translated by the Targum: שׁוֹשְׁבִינֵיהּ his best man.
