Genesis 13:9

אם השמאל ואימינה IF THOU WILT TAKE THE LEFT HAND, THAN I WILL GO TO THE RIGHT —Wherever you settle down I will not go far from you and I will stand by you as a shield and as a helper. Ultimately, indeed, he (Lot) was really in need of him, as it is said, (Genesis 14:14) “And Abram heard that his brother was taken captive etc.” ואימינה I WILL GO TO THE RIGHT — The word means “I will direct myself towards the right”, just as ואשמאילה means “I will direct myself towards the left.” If you say that it should be punctuated וְאַיְמִינָה (the regular Hiphil form) I answer that in another place also we find this form, (2 Samuel 14:19) אם יש לְהֵמִין “none can turn to the right hand”, where the punctuation is not לְהַיְמִין.

הֲלֹ֤א כׇל־הָאָ֙רֶץ֙ לְפָנֶ֔יךָ הִפָּ֥רֶד נָ֖א מֵעָלָ֑י אִם־הַשְּׂמֹ֣אל וְאֵימִ֔נָה וְאִם־הַיָּמִ֖ין וְאַשְׂמְאִֽילָה׃

Is not the whole land before thee? separate thyself, I pray thee, from me: if thou wilt take the left hand, then I will go to the right; or if thou depart to the right hand, then I will go to the left.
