וַיֹּ֤אמֶר אֲלֵהֶם֙ אַל־תְּאַחֲר֣וּ אֹתִ֔י וַֽיהוָ֖ה הִצְלִ֣יחַ דַּרְכִּ֑י שַׁלְּח֕וּנִי וְאֵלְכָ֖ה לַֽאדֹנִֽי׃
Y él les dijo: No me detengáis, pues que SEÑOR ha prosperado mi camino; despachadme para que me vaya á mi señor.
Rashbam
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
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. אל תאחרו אותי, By delaying her departure you would be delaying my return home. שלחוני, let me depart with the girl, ואלכה לאדוני, and I will go to my master as he has commanded me in order to bring him a wife for his son. How could I possibly return empty-handed?
