“It is the LORD's Passover”
You must be fully dressed for travel, with your sandals on your feet and your staff in your hand. You are to eat in haste; it is the LORD's Passover. (Exodus 12:11 BSB)
What it sounds like today
Dinner instructions with an oddly urgent dress code.
The cultural key
The meal is eaten standing, belt fastened, sandals on, staff in hand, the posture of people ready to move at a moment's notice, because the exodus would begin that night. The name Passover (pesach) comes from the LORD 'passing over' the blood-marked homes. This urgent, travel-ready meal became an annual reenactment: every generation would eat it as though they themselves were leaving Egypt, and 'dressed for action, with your lamps burning' becomes a New Testament image for readiness.
Recovered meaning
The first Passover is eaten on the move, a meal for people about to be set free that very night. Reenacted yearly, it trained Israel to remember the exodus as its own, and gave Jesus the table he would transform into the Lord's Supper.
