Verse 19 “And Moses took the bones of Joseph with him: for he had straitly sworn the children of Israel, saying, God will surely visit you; and ye shall carry up my bones away hence with you.”
Moses took the remains of Joseph out of Egypt with him, just as Joseph had commanded the Jews to do (Gen. 50:25). This reminds us that when Jesus comes in the air to rapture us, He will take the dead in Christ out of this world and will not leave a single bone of one of His redeemed for the Devil to brag about.
