Nehemiah 9:20 "You, in Your great compassion,Did not forsake them in the wilderness; The pillar of cloud did not leave them by day, To guide them on their way, Nor the pillar of fire by night, to light for them the way in which they were to go. 20 “You gave Your good Spirit to instruct them, Your manna You did not withhold from their mouth,
And You gave them water for their thirst."
First, the "it" in Exodus 12:6 is noneother than the Passover lamb, that every family was to slaughter and later on in the Mosaic law would specifically be done by a qualified Levitical priest (Leviticus 23; Deuteronomy 16:1-2).
Second, the "fourteenth day" of the month corresponded to March or April on our calendars. Now with the details thus far seen, we have foreshadowed the Lamb of God, spoken of by John the Baptist in John 1:29 and the timing of when He was to be crucified.
The third detail we find in Exodus 12:6 is with reference to the whole congregation of Israel. The Passover lamb was given on behalf of each family and in a representative way the whole of God's people. We know when Jesus came to this world, He did indeed come to die for the whole world in one respect as the Historically given Savior who is offered to all men indiscriminately in the Gospel (1 John 2:1-2). However in a specific, saving way, Jesus died for His church, composed of all whom God set His Spirit to work and who by faith responded to such work (Acts 20:28; 1 Timothy 4:10).
And You gave them water for their thirst." Jesus would 450 years after Nehemiah reveal how He was the fulfillment of the meaning foreshadowed in God's giving of Manna. In John 6, Jesus revealed Himself to be the Bread of Life. To be more specific, John 6:58-63 records Jesus saying - "This is the bread which came down out of heaven; not as the fathers ate and died; he who eats this bread will live forever." 59 These things He said in the synagogue as He taught in Capernaum.
60 Therefore many of His disciples, when they heard thissaid, “This is a difficult statement; who can listen to it?”61 But Jesus, conscious that His disciples grumbled at this, said to them, “Does this cause you to stumble? 62 What then if you see the Son of Man ascending to where He was before? 63 It is the Spirit who gives life; the flesh profits nothing; the words that I have spoken to you are spirit and are life."
