2Ki 11:16

Thus they made way for her on both sides, or, according to the correct explanation given by the Chaldee, ידים להּ ישׂימוּ, they formed lines (Spalier, fences) and escorted her back, and she came by the way of the horses’ entrance into the palace, and was there put to death. הסּוּסים מבוא is explained in the Chronicles by הסּוּסים שׁער מבוא, entrance of the horse-gate. The entrance for the horses, i.e., the way which led to the royal mews, is not to be identified with the horse-gate mentioned in Neh 3:28; for this was a gate in the city wall, whereas the road from the temple to the royal mews, which were no doubt near the palace, was inside the wall.
