As we looked we saw God uttered "tomorrow" each other time. As I counted the verses there were seven in all. Seven! 8:23, 29; 9:5, 18 and 10:4 all refer to God's plan to act tomorrow. There are five total. However, it is the next two which make things interesting.
Exodus 13:14 "And when in time to come your son asks you, 'What does this mean?' you shall say to him, 'By strength of hand the LORD brought us out of Egypt, from the house of bondage."
The sixth reference is to the Passover. The sixth day, Friday, is the day man is created. It is also the crucifixion day. (This is part of the deeper meaning of 666, it is the number of man.) The Passover is the culmination of the new creation of Israel in the Exodus, it is when God creates the new man--Israel--His son. Passover, according to Jesus, is an icon of His own crucifixion and the covenant in His blood. The death of the Son of Man on Good Friday is the culmination of the new creation in Jesus. Day six and new creation are a deeper meaning of the text.
The seventh use of tomorrow in in 16:23 "This is what the LORD has commanded: 'Tomorrow is a day of solemn rest, a holy Sabbath unto the LORD; bake what you will bake and boil what you will boil, and all that is left over lay by to be kept till the morning.'" Sabbath is the seventh day. It ends the week of creation. It is a time to refrain from the busyness and business of life and be present to the deeper meaning of reality. This verse is found in the chapter on the Bread of Heaven, where God rains down manna upon the people. Manna, of course, is connected to eucharist (see John 6, "I am the Bread of Life"). The Passover meal (in the Synoptics) is where Jesus says His flesh is bread, His blood is wine. With the seventh appearance of the word we come to closure on the new creation. The chapters "Bread from Heaven" (ch16) and "Water from the Rock" (ch17) immediately follow the Song of Moses, which celebrates the escape from Egypt, and form the triple grace of salvation: rescue from death by Egypt, hunger and thirst. The next appearance of 'tomorrow' is the beginning of the new day, the battle with Amalek, where Moses stands on the Mountain and as long as his hands are raised the Israelites win. Perhaps this is Day 8, the new week and the battles of living the faith?
So what? I think the deeper revelation is new creation. With 'seven tomorrows' culminating in Passover and Sabbath, I believe we hear whispers of the Christ events of our salvation. This is the Scripture which Jesus fulfills/fills up. These deeper verbal hints and pointers lead us to encounter the New Creation/Salvation in Jesus. It is why the ancient church said that the literal meaning of Scripture is not the most important, that a Divine Word has deeper meanings.
It is why I never grow weary of studying to find the depth of artistry in revelation and the amazing confirmation of the faith in the word.
