Exodus 2:6

And when she had opened it ,.... The ark, for it was shut or covered over, though doubtless there were some apertures for respiration:

she saw the child in it , and, behold, the babe wept ; and which was a circumstance, it is highly probable, greatly affected the king's daughter, and moved her compassion to it; though an Arabic writer says F16 Patricides apud Hottinger. p 401. , she heard the crying of the child in the ark, and therefore sent for it:

and she had compassion on him, and said, this is one of the Hebrews' children ; which she might conclude from its being thus exposed, knowing her father's edict, and partly from the form and beauty of it, Hebrew children not being swarthy and tawny as Egyptian ones: the Jewish writers F17 T. Bab. Sotah, fol. 12. 2. Aben Ezra in loc. say, she knew it by its being circumcised, the Egyptians not yet using circumcision.
