Gen 30:33

וְעָֽנְתָה־בִּ֤י צִדְקָתִי֙ בְּי֣וֹם מָחָ֔ר כִּֽי־תָב֥וֹא עַל־שְׂכָרִ֖י לְפָנֶ֑יךָ כֹּ֣ל אֲשֶׁר־אֵינֶנּוּ֩ נָקֹ֨ד וְטָל֜וּא בָּֽעִזִּ֗ים וְחוּם֙ בַּכְּשָׂבִ֔ים גָּנ֥וּב ה֖וּא אִתִּֽי׃

So my honesty will testify for me when you come to check on my wages in the future. If I have any goats that are not speckled or spotted, or any lambs that are not dark-colored, they will be considered stolen.”
