Every son that is born. — The LXX. add “to the Hebrews,” but without any necessity, since the context shows that only Hebrew children are meant.
Ye shall cast into the river. — Infanticide, so shocking to Christians, has prevailed widely at different times and places, and been regarded as a trivial matter. In Sparta, the State decided which children should live and which should die. At Athens a law of Solon left the decision to the parent. At Rome, the rule was that infants were made away with, unless the father interposed, and declared it to be his wish that a particular child should be brought up. The Syrians offered unwelcome children in sacrifice to Moloch; the Carthaginians to Melkarth. In China infanticide is said to be a common practice at the present day. Heathen nations do not generally regard human life as sacred. On the contrary, they hold that considerations of expediency justify the sweeping away of any life that inconveniences the State. Hence infanticide is introduced by Plato into his model republic (Rep. v. 9). Almost all ancient nations viewed the massacre of prisoners taken in war as allowable. The Spartan crypteia was a system of licensed murder. The condemnation to death of all male Hebrew children by Pharaoh is thus in no respect improbable. On the other hand, the mode of the death presents difficulties. For, first, the Nile was viewed as a god; and to fill it with corpses would, one might have supposed, have been regarded as a pollution. Secondly, the Nile water was the only water drunk; and sanitary considerations might thus have been expected to have prevented the edict. Perhaps, however, the children were viewed as offerings to the Nile, or to Savak, the crocodile headed god, of whom each crocodile was an emblem. At any rate, as the Nile swarmed with crocodiles throughout its whole course, the bodies were tolerably sure to be devoured before they became putrescent.
