זֶה־לִּ֞י עֶשְׂרִ֣ים שָׁנָה֮ בְּבֵיתֶךָ֒ עֲבַדְתִּ֜יךָ אַרְבַּֽע־עֶשְׂרֵ֤ה שָׁנָה֙ בִּשְׁתֵּ֣י בְנֹתֶ֔יךָ וְשֵׁ֥שׁ שָׁנִ֖ים בְּצֹאנֶ֑ךָ וַתַּחֲלֵ֥ף אֶת־מַשְׂכֻּרְתִּ֖י עֲשֶׂ֥רֶת מֹנִֽים׃
Sudah dua puluh tahun aku tinggal di rumahmu. Aku bekerja untukmu empat belas tahun demi kedua anak perempuanmu dan enam tahun demi kambing dombamu, tetapi engkau telah mengubah upahku sepuluh kali.
Avodah Zarah
Papa said: If a Tanna is uncertain about the details [of what exact year it is] let him ask a notary what year it is according to his reckoning and add twenty to it and he will find his calculation. As a mnemonic sign take the verse, “Thus I have been twenty years in Your house” (Genesis 31:41).
