Targum for Genesis 31:41

זֶה־לִּ֞י עֶשְׂרִ֣ים שָׁנָה֮ בְּבֵיתֶךָ֒ עֲבַדְתִּ֜יךָ אַרְבַּֽע־עֶשְׂרֵ֤ה שָׁנָה֙ בִּשְׁתֵּ֣י בְנֹתֶ֔יךָ וְשֵׁ֥שׁ שָׁנִ֖ים בְּצֹאנֶ֑ךָ וַתַּחֲלֵ֥ף אֶת־מַשְׂכֻּרְתִּ֖י עֲשֶׂ֥רֶת מֹנִֽים׃

These twenty years have I been in thy house: I served thee fourteen years for thy two daughters, and six years for thy flock; and thou hast changed my wages ten times.
