So far interesting but lacking important information when being considered, not the OP's lack either. First the Bible is the Book of Books and is of a single context from "In the beginning..." through the very last word of Revelation 22. It has many nuances but the overall message is Salvation Jesus, the Christ.
The answer is simple, God did not seek to kill Moses before Moses had competed his mission, if He had, Moses would have fallen and there never would have been an exodus led by the same and on this incorrect set of assumptions might never have been an exodus led by anyone. But that is in no fashion true.
When reading any of these odd (only to us) statements we must return to our first love. Always remember that God's attributes include two duzies that must not, ever, be forgotten. God is Omnipotent, There iis nothing God cannot do. And the second is the point we must center on to begin to wrap our heads around many of the saying God has preserved for us to learn of Him.
the fact that God reveals He is Omniscient changes everything. With his Omniscience comes Omnipresence!
There are a list of reasons to know this that are found in His working in the scriptures and our lives. The important one here is notable when it is declared that a day to God is as a thousand years to a man or to man. Couple that with Genesis 1 through 3 and the picture can begin to form in your mind. There is nothing in this Space/Time Continuum that Jesus/God did not create. (John 1:1-3) The Time/Space Continuum is strictly for our benefit. God did not need it before He created it and He does not need it now,, in fact God was and is still outside the Continuum but being Omniscient, He is also in it. In Psalm 139 we see the author asking God where can he possibly hide from Him because He is already there.
This omniscience is a very interesting subject, all on it's own. I means God is literally everywhere at every time. this does rip the Calvinist's wording to explain Predestination apart but it also, in no manner proves the Armenian ideas either. and that's good because Predestination is scriptural and if it is in the Scriptures, it is truth.
But, back on point before I call this a Sunday School Classd and get everyone upset with me, like this message won't, right? soi with ning bound within our Time/Space Continuum and His Omniscience god is with you as you read this message, He has always been in the past and He is, right now, in the future, and always has been. Wanna Time Travel? Convince God to hold your hand! Of course He won't do that but it is a vain thought many will think. God knew the very moment I would repent and devote my life to Him because time is meaningless to His Holiness. Before the clock began to run, before God created the first spec of space or earth, He wrote the Book of Life because he knew.
And pretenders? If you are not the real item, you want to change that, now, God can call at any moment making it eternally too late for the Rapture. May god bless each of you with His knowledge.
