The Hebrew Scriptures were written in the first place for the fleshly nation of Israel during the time that they had a special relationship with God.
وَهكَذَا أَضَافَ يَهْوَه ٱلْأَسْفَارَ ٱلْيُونَانِيَّةَ ٱلْمَسِيحِيَّةَ ٱلْمُوحَى بِهَا إِلَى ٱلْأَسْفَارِ ٱلْعِبْرَانِيَّةِ ٱلْمُلْهَمَةِ ٱلْمَوْجُودَةِ قَبْلًا .‏
