11 'And it hath been, when Jehovah bringeth thee in unto the land of the Canaanite, as He hath sworn to thee and to thy fathers, and hath given it to thee, 12 that thou hast caused every one opening a womb to pass over to Jehovah, and every firstling—the increase of beasts which thou hast: the males 'are' Jehovah's. 13 'And every firstling of an ass thou dost ransom with a lamb, and if thou dost not ransom 'it', then thou hast beheaded it: and every first-born of man among thy sons thou dost ransom. 14 'And it hath been, when thy son asketh thee hereafter, saying, What 'is' this? that thou hast said unto him, By strength of hand hath Jehovah brought us out from Egypt, from a house of servants; 15 yea, it cometh to pass, when Pharaoh hath been pained to send us away, that Jehovah doth slay every first-born in the land of Egypt, from the first-born of man even unto the first-born of beast; therefore I am sacrificing to Jehovah all opening a womb who 'are' males, and every first-born of my sons I ransom; 16 and it hath been for a token on thy hand, and for frontlets between thine eyes, for by strength of hand hath Jehovah brought us out of Egypt.'

The Pillar of Cloud and the Pillar of Fire

17 And it cometh to pass in Pharaoh's sending the people away, that God hath not led them the way of the land of the Philistines, for it 'is' near; for God said, 'Lest the people repent in their seeing war, and have turned back towards Egypt;' 18 and God turneth round the people the way of the wilderness of the Red Sea, and by fifties have the sons of Israel gone up from the land of Egypt. 19 And Moses taketh the bones of Joseph with him, for he certainly caused the sons of Israel to swear, saying, 'God doth certainly inspect you, and ye have brought up my bones from this with you.' 20 And they journey from Succoth, and encamp in Etham at the extremity of the wilderness, 21 and Jehovah is going before them by day in a pillar of a cloud, to lead them in the way, and by night in a pillar of fire, to give light to them, to go by day and by night;

Commentary on Exodus 13:11-16

(Read Exodus 13:11-16)

The firstlings of beast not used in sacrifice, were to be changed for others so used, or they were to be destroyed. Our souls are forfeited to God's justice, and unless ransomed by the sacrifice of Christ, will certainly perish. These institutions would continually remind them of their duty, to love and serve the Lord. In like manner, baptism and the Lord's supper, if explained and attended to, would remind us, and give us occasion to remind one another of our profession and duty.

Commentary on Exodus 13:17-20

(Read Exodus 13:17-20)

There were two ways from Egypt to Canaan. One was only a few days' journey; the other was much further about, through the wilderness, and that was the way in which God chose to lead his people Israel. The Egyptians were to be drowned in the Red sea; the Israelites were to be humbled and proved in the wilderness. God's way is the right way, though it seems about. If we think he leads not his people the nearest way, yet we may be sure he leads them the best way, and so it will appear when we come to our journey's end. The Philistines were powerful enemies; it was needful that the Israelites should be prepared for the wars of Canaan, by passing through the difficulties of the wilderness. Thus God proportions his people's trials to their strength, 1 Corinthians 10:13. They went up in good order. They went up in five in a rank, some; in five bands, so others, which it seems rather to their faith and hope, that God would bring them to Canaan, in expectation of which they carried these bones with them while in the desert.

(Read Exodus 13:21-22)

The Lord went before them in a pillar, or appearance of the Divine Majesty. Christ was with the church in the wilderness, John 14:6.
