Genesis 50:17

שא נא לפשע עבדי אלהי אביך NOW, PRAY, FORGIVE THE TRESSPASS OF THE SERVANTS OF THE GOD OF THY FATHER — After having repeated to Joseph the words which his brothers stated had been their fathers message, “forgive thy brothers’ sin” the messengers were to add as a petition of the brothers “Now, pray etc.”, meaning “If you will not forgive them although they are your brothers, forgive them because they are the servants of the God of thy father”, implying though your father be dead, his God still lives and they are his servants.

כֹּֽה־תֹאמְר֣וּ לְיוֹסֵ֗ף אָ֣נָּ֡א שָׂ֣א נָ֠א פֶּ֣שַׁע אַחֶ֤יךָ וְחַטָּאתָם֙ כִּי־רָעָ֣ה גְמָל֔וּךָ וְעַתָּה֙ שָׂ֣א נָ֔א לְפֶ֥שַׁע עַבְדֵ֖י אֱלֹהֵ֣י אָבִ֑יךָ וַיֵּ֥בְךְּ יוֹסֵ֖ף בְּדַבְּרָ֥ם אֵלָֽיו׃

So shall you say to Yosef, Forgive, I pray thee now, the trespass of thy brothers, and their sin; for they did evil to thee: and now, we pray thee, forgive the trespass of the servants of the God of thy father. And Yosef wept when they spoke to him.
