וַ⁠יַּ֨עַן דָּוִ֜ד אֶת־רֵכָ֣ב ׀ וְ⁠אֶת־בַּעֲנָ֣ה אָחִ֗י⁠ו בְּנֵ֛י רִמּ֥וֹן הַ⁠בְּאֵֽרֹתִ֖י וַ⁠יֹּ֣אמֶר לָ⁠הֶ֑ם

The expression and he said to them introduces a direct quotation. In your translation, use a natural way of introducing direct quotations in your language. It may not be necessary to represent this expression explicitly. Alternate translation: [But David responded to Rechab and Baanah his brother, the sons of Rimmon the Beerothite]
