데바림 (신명기) 4:37

ותחת כי אהב AND BECAUSE HE LOVED — i.e., and all this was because He loved thy fathers. ויוצאך בפניו AND HE BROUGHT THEE OUT BEFORE HIM — like a man who leads his son before him, as it is said, (Exodus 14:19) “And the angel of the Lord that went [before them] moved and went behind them" (see Rashi on that verse). — Another explanation of ויוצאך בפניו AND HE BROUGHT THEE FORTH IN HIS PRESENCE: — i.e. in the presence of his fathers, as it is said, (Psalms 78:12; see Rashi on that verse), “In the presence of their fathers He did wonders". Do not be surprised that it refers to them (the fathers) in the singular number (by בפניו), for you see it has already written about them in the singular number, viz., “And he chose his seed after him" (instead of “their seed after them").

וְתַ֗חַת כִּ֤י אָהַב֙ אֶת־אֲבֹתֶ֔יךָ וַיִּבְחַ֥ר בְּזַרְע֖וֹ אַחֲרָ֑יו וַיּוֹצִֽאֲךָ֧ בְּפָנָ֛יו בְּכֹח֥וֹ הַגָּדֹ֖ל מִמִּצְרָֽיִם׃

And because he loved thy fathers, therefore, he chose their seed after them, and brought thee out, he himself being present, with his mighty power out of Miżrayim;
