What does Exodus 13:9 mean?
God has commanded Israel to teach future generations about their liberation from Egyptian slavery (Exodus 1:11–14; 12:40–41). This is the primary purpose of celebrations such as Passover (Exodus 12:11) and the Feast of Unleavened Bread (Exodus 13:6–8). The Lord used His power (Exodus 3:19–20) to free His people (Deuteronomy 14:2) and they were obligated to remember this for all time. This verse is meant to emphasize the importance of understanding Israel's history and what it means. Such things should influence everything the Israelites think, see, and do, and should always be part of their understanding.Later, some Jewish people would take these expressions regarding hands and eyes very literally (Exodus 13:16). They would begin wearing tefillin—also called "phylacteries"—which are small boxes containing written Scripture. Common inclusions for these boxes are this very passage (Exodus 13:2–10), the Shema (Deuteronomy 6:4–9), or Deuteronomy 11:13–21. By the time of Jesus' earthly ministry, these had become showy, shallow acts of pride, rather than of remembrance (Matthew 23:5).
Exodus 13:1–10 starts with a command for consecration of all Israel's firstborn. It then gives further instructions about the Feast of Unleavened Bread. This is a week-long observance which celebrates God's work to free Israel from Egyptian slavery. Eating bread with no leaven—without yeast—symbolizes being free from the pervasive effects of sin. It also recalls how the people prepared un-risen bread on the night they were freed (Exodus 12:8, 39).
God reiterates the requirements of the Feast of Unleavened Bread. Israel is to celebrate this every year as a way of remembering their liberation from Egyptian slavery. In addition, the people are to consecrate all of the first-born of any mother—both people and animals. Animals that cannot be sacrificed are to be redeemed. Sons are to be redeemed by an animal sacrifice. The Lord creates a column of clouds for the people to follow during the day, which is lit by fire so they can also follow it at night. This keeps them moving quickly. Soon, Egyptian soldiers will catch up to them and God will once again provide miraculous rescue (Exodus 14).
