וְעָֽנְתָה־בִּ֤י צִדְקָתִי֙ בְּי֣וֹם מָחָ֔ר כִּֽי־תָב֥וֹא עַל־שְׂכָרִ֖י לְפָנֶ֑יךָ כֹּ֣ל אֲשֶׁר־אֵינֶנּוּ֩ נָקֹ֨ד וְטָל֜וּא בָּֽעִזִּ֗ים וְחוּם֙ בַּכְּשָׂבִ֔ים גָּנ֥וּב ה֖וּא אִתִּֽי׃
후일에 외삼촌께서 오셔서 내 품삯을 조사하실 때에 나의 의가 나의 표징이 되리이다 내게 혹시 염소 중 아롱지지 아니한 자나 점이 없는 자나 양 중 검지 아니한 자가 있거든 다 도적질한 것으로 인정하소서
Rashi on Genesis
'וענתה בי וגו AND MY RIGHTEOUSNESS SHALL ANSWER FOR ME etc. — Should you suspect me of taking any animals that are yours my righteousness will answer for me, — for my righteousness will come and bear witness before thee as to my hire that you will find in my herd only speckled and spotted ones. Whatever, however, you find amongst them (amongst the animals) that is not speckled or spotted or brownish it will be certain that I have stolen it from your flocks and that it is in my possession by way of theft.
Sforno on Genesis
My righteousness … when it comes before you. Or, “When my righteousness shall go to show my wage, it will testify before you” — i.e., Hashem will reveal what Yaakov deserves for his faithful service by altering the coloration of the lambs.
