Isaiah 41:3

And passed safely "He passeth in safety" - The preposition seems to have been omitted in the text by mistake; the Septuagint and Vulgate seem to have had it in their copies; εν ειρηνῃ, to pace, בשלום beshalom, "prosperously." It is so in one of De Rossi's MSS.

He pursued them - When they were driven away. He followed on, and devoted them to discomfiture and ruin.

And passed safely - Margin, as Hebrew, 'In peace.' That is, he followed them uninjured; they had no power to rally, he was not led into ambush, and he was safe as far as he chose to pursue them.

Even by the way that he had not gone with his feet - By a way that he had not been accustomed to march; in an unusual journey; in a land of strangers. Cyrus had passed his early years on the east of the Euphrates. In his conquests he crossed that river, and extended his march beyond even the river Halys to the western extremity of Asia, and even to Egypt and the Red Sea. The idea here is, that he had not traveled in these regions until he did it for purposes of conquest - an idea which is strictly in accordance with the truth of history.

41:3 Pursued - Went on in the pursuit with ease and safety.Even - Through unknown paths.
