וַיֹּ֤אמֶר אֲלֵהֶם֙ אַל־תְּאַחֲר֣וּ אֹתִ֔י וַֽיהוָ֖ה הִצְלִ֣יחַ דַּרְכִּ֑י שַׁלְּח֕וּנִי וְאֵלְכָ֖ה לַֽאדֹנִֽי׃
And he said unto them: ‘Delay me not, seeing the LORD hath prospered my way; send me away that I may go to my master.’
Rashbam on Genesis
וה' הצליח דרכי, clearly G’d does not want that the matter suffer any delay seeing that something which experiences delay, obstacles, cannot truly be considered as being successful.
Radak on Genesis
ויאמר אליהם, seeing that it is clear that G’d has made my mission successful, do not cause me any delay of even a single day.
Radak on Genesis
אל תאחרו אותי, By delaying her departure you would be delaying my return home.
