Commentary for II Samuel 19:27

וַיֹּאמַ֕ר אֲדֹנִ֥י הַמֶּ֖לֶךְ עַבְדִּ֣י רִמָּ֑נִי כִּֽי־אָמַ֨ר עַבְדְּךָ֜ אֶחְבְּשָׁה־לִּי֩ הַחֲמ֨וֹר וְאֶרְכַּ֤ב עָלֶ֙יהָ֙ וְאֵלֵ֣ךְ אֶת־הַמֶּ֔לֶךְ כִּ֥י פִסֵּ֖חַ עַבְדֶּֽךָ׃

And he answered: ‘My lord, O king, my servant deceived me; for thy servant said: I will saddle me an ass, that I may ride thereon, and go with the king; because thy servant is lame.
