רַק֮ לֹא־יַרְבֶּה־לּ֣וֹ סוּסִים֒ וְלֹֽא־יָשִׁ֤יב אֶת־הָעָם֙ מִצְרַ֔יְמָה לְמַ֖עַן הַרְבּ֣וֹת ס֑וּס וַֽיהוָה֙ אָמַ֣ר לָכֶ֔ם לֹ֣א תֹסִפ֗וּן לָשׁ֛וּב בַּדֶּ֥רֶךְ הַזֶּ֖ה עֽוֹד׃
Only he shall not multiply horses to himself, nor cause the people to return to Egypt, to the end that he should multiply horses; forasmuch as the LORD hath said unto you: ‘Ye shall henceforth return no more that way.’
Targum Jonathan on Deuteronomy
Only let him not increase to him more than two horses, lest his princes ride upon them, and become proud, neglect the words of the law, and commit the sin of the captivity of Mizraim; for the Lord hath told you, By that way ye shall return no more.
