What does Exodus 13:16 mean?
Over time, ancient Israel developed the practice of wearing teffilin: small containers of scripture strapped to the forearm and forehead. This tradition was inspired by verses such as this, as well as others using the same figure of speech (Exodus 13:9; Deuteronomy 6:8–9; 11:13–21). God's chosen people (Deuteronomy 14:2) were to maintain a constant awareness of His truth and all that He had done for them. That relationship was to be part of everything they saw, thought, or did. God did not necessarily mean that His people were to physically attach these words to their bodies. During Jesus' earthly life, this practice had become a prideful display instead of a remembrance (Matthew 23:5).God's "strong hand" was responsible for Israel's freedom from slavery (Exodus 1:11–14; 12:40–41). Egypt was never going to release their captives without tremendous pressure (Exodus 3:19–20). So, God sent supernatural disasters (Exodus 7:21; 8:6, 17, 24; 9:6, 10, 24; 10:14, 23). None were enough until the last plague. The Lord killed all of Egypt's firstborn (Exodus 11:4–6). Only then did Pharaoh give the Hebrews an unconditional release (Exodus 12:29–32).
