Exodus 13:17

“And it came to pass, when Pharaoh had let the people go, etc.] Gave them leave to depart out of Egypt, and even urged them to be gone in haste upon the death of his firstborn: that God led them not through the way of the land of the Philistines, although that was near; the land of the Philistines was the Pentapolis, or five cities of Gaza, Ashkelon, Ashdod, Ekron, and Gath, which lay between Egypt and Canaan; and their way through it to Canaan, out of Egypt, was the nearest they could go; and was, as Aben Ezra says, about ten days’ journey; but Philo the Jew says f400 it was but three days’ journey; and it seems, by the sons of Jacob going to and fro for corn, that it was no very long…”

“JOURNEY FROM EGYPT. (Exo 13:17-21) God led them not through the way of the land of the Philistines, although that was near, &c.--The shortest and most direct route from Egypt to Palestine was the usual caravan road that leads by Belbeis, El-Arish, to Ascalon and Gaza. The Philistines, who then possessed the latter, would have been sure to dispute their passage, for between them and the Israelites there was a hereditary feud (Ch1 7:21-22); and so early a commencement of hostilities would have discouraged or dismayed the unwarlike band which Moses led. Their faith was to be exercised and strengthened, and from the commencement of their travels we observe the same careful proportion of burdens…”

“13:17–14:4 The Lord’s redemptive power was demonstrated as he brought Israel into a place where they were completely helpless and had to either rely on him for rescue or die. Although at the time it must have seemed completely foolish, Israel would thank God for the rest of its history for maneuvering them into such a spot (see Ps 106:7-12; cp. Isa 12:2-6). 13:17-18 faced with a battle: The Israelites had not yet seen God fight on their behalf. Even though they left Egypt like an army ready for battle (13:18; see also 12:51), it was only an appearance. Until they experienced the Lord as fighting for them (14:14) in the crossing of the sea, they were not ready to face enemies in the Promised…”

“the people repent: Exo 14:11, Exo 14:12; Num 14:1-4; Deu 20:8; Jdg 7:3; Kg1 8:47; Luk 14:27-32; Act 15:38 return: Exo 16:2, Exo 16:3; Deu 17:16; Neh 9:17; Act 7:39 Exodus 13:18”

“Journey from Succoth to Etham. - Succoth, Israel's first place of encampment after their departure, was probably the rendezvous for the whole nation, so that it was from this point that they first proceeded in an orderly march. The shortest and most direct route from Egypt to Canaan would have been by the road to Gaza, in the land of the Philistines; but God did not lead them by this road, lest they should repent of their movement as soon as the Philistines opposed them, and so desire to return to Egypt, פּן: μή, after אמר to say (to himself), i.e., to think, with the subordinate idea of anxiety. The Philistines were very warlike, and would hardly have failed to resist the entrance of the…”
