Sung Psalm 114 (note ref to Jordan Crossing v3)
Read Joshua 5
Some other references to Passover in Pentateuch were checked Ex.34:23,25, Num. 33:3 and Deut. 16 (repeats).
Key N.T. refs. are I Cor.5:7 and Heb.11:28. Note that keeping the Passover was by faith (obedience to word of God to do an otherwise foolish-looking thing).
Joshua was courageous by keeping God’s law (Josh.1:8,9)
We come to Gilgal, the third Passover, after the first in Egypt and second at Mt. Sinai. Circumcision was mandatory so we have perhaps the largest mass circumcision ever with upwards of 600,000 males taking part, perhaps as many as a million (Josh.5:2 c.f. Ex.12:44).
Why had there been no circumcisions in the wilderness? We know that there was idolatry in the camp (Amos 5:25,26, Acts 7:43). Was there any piety? Yes (Jer.2:2,3).
Note the two sacraments together, one signifying entry into the covenant community and the other of keeping the covenant. Today we have the N.T. equivalents namely baptism and Lord’s Supper (conjoined in I Cor.10:2).
At the end of the chapter Joshua is commissioned by Christ appearing as a Christophany very similar to Moses at the burning bush.
