His sons. — The pronoun refers to the subject of Daniel 11:9, which is the northern king (though, according to the LXX. and English Version, it must be his rival). There is a marginal alternative in the Hebrew “son.” The LXX. supports the text. If the king of the north last mentioned is Seleucus Callinicus, his sons must be Seleucus Ceraunus, a man of no importance, and Antiochus the Great. It is here stated of the sons that they are stirred up; that they collect a vast army, which advances steadily, overflowing like a torrent, while its masses pass through the land; that they shall return and carry on the war up to the frontier of the southern king. Considering the uncertainty of the readings in the Hebrew text, and the ambiguity of the language, this is anything but a definite statement. However, it has been explained to refer to the wars of Antiochus and Ptolemy Philopator, in course of which they took Seleucia, Tyre, and Ptolemais, besieged the Egyptians in Sidon, and actually took possession of Gaza.
One shall certainly come. — Not the king, but the multitude just spoken of. The words “overflow,” “pass through” “return,” all refer to the ebbing and flowing of the tide of war.
