In this week's פרשה, we find בני ישראל are confronted militarily by סיחון. The פסוק states כ"א:כ"ג ויבא יהצה. The question is, what was the name of the place? Was it יהץ and the pasuk is stating that he came to יהץ and the suffix ה implies to? Or is the name of the place actually יהצה?
The הפטרה appears to settle this quite unequivocally. In שופטים י"א:כ it states ויחנו ביהצה. That seems quite clear that the name of the place is יהצה. However, shockingly, אונקלוס in our פרשה renders ואתא ליהץ (as well as in דברים ב:לב)!!
תרגום יונתן in שופטים renders ושרו ביהצה.
Thank you to R' Ari Storch for pointing this out.
