C. F. Keil and Franz Delitzsch on Exodus 13:3-7

Exo 13:3-7

The directions as to the seven days’ feast of unleavened bread (Exo 12:15-20) were made known by Moses to the people on the day of the Exodus, at the first station, namely, Succoth; but in the account of this, only the most important points are repeated, and the yearly commemoration is enjoined. In Exo 13:3, Egypt is called a “slave-house,” inasmuch as Israel was employed in slave-labour there, and treated as a slave population (cf. Exo 20:2; Deu 5:6; Deu 6:12, etc.). יד הזק “strength of hand,” in Exo 13:3, Exo 13:14, and Exo 13:16, is more emphatic than the more usual חזקה יד (Exo 3:19, etc.). - On Exo 13:5, see Exo 3:8, and Exo 12:25. In Exo 13:6, the term “feast to Jehovah” points to the keeping of the seventh day by a holy convocation and the suspension of work (Exo 12:16). It is only of the seventh day that this is expressly stated, because it was understood as a matter of course, that the first was a feast of Jehovah.
