Painted her face - literally, “put her eyes in antimony “ - i. e., dyed the upper and under eyelids, a common practice in the East, even at the present day. The effect is at once to increase the apparent size of the eye, and to give it unnatural brilliancy. Representations of eyes thus embellished occur on the Assyrian sculptures, and the practice existed among the Jews (marginal reference; and Jeremiah 4:30).
Tired her head - Dressed (attired) her head, and no doubt put on her royal robes, that she might die as became a queen, in true royal array.
A window - Rather, “the window.” The gate-tower had probably, as many of those in the Assyrian sculptures, one window only.
