In today's daily bread (Exodus 39) is found the meaning of the call to "clothe" oneself with Christ (Ro 13:14; Gal 3:27), that is living by faith in the LORD who saves his people from their sins and makes them right with God the Father so they can live as his royal princes and princesses.
The Ephod was to be made of thin sheets of pure gold and cut strands to be worked into blue (holiness) purple (royalty) and scarlet (color of our sin) yarn of fine linen (made righteous with the sinless blood of the Lord).
Upon sinning Adam and Eve realized that they were naked so they started to cover themselves. And they hid (from the Lord). They lost their identity as God's children.
But in Jesus the Redeemer God the Father restores the sinners back to Him granting them the standing of His children so they could live in Him without fear and serve Him with joy!
