I am fairly certain you are referencing David Wolfe, Wolfpe? and Christopher Hitchens. Jewish thinking on the old testament is a long way from talmudic rationale. Jews, per capita, are maybe the most secular group on Earth, especially across Europe and the US.
On God's omniscience
Romans 8:38-39New International Version (NIV)
38 For I am convinced that neither death nor life, neither angels nor demons,a] neither the present nor the future, nor any powers, 39 neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
Psalms 149:1-3 illuminates this view further, and makes God's omniscience personal to humans
1 O Lord, you have searched me and known me!
2 You know when I sit down and when I rise up;
you discern my thoughts from afar.
You search out my path and my lying down
and are acquainted with all my ways.
Psalms 139:5 says
“You hem me in, behind and before,
and lay your hand upon me.”
Psalms 147:4-5 states
4 He counts the number of the stars;
He calls them all by name. 5 Great is our Lord, and i mighty in power;
His understanding is infinite.
Now, on numerous occasions, God purposefully, and directly sends people on missions, like Joseph. Joesph tells his brothers that God put him into slavery by their hand for a specific reason.
God even goes as far as to know the hairs on your head. The Bible does not leave any room for a God that explodes in creativity, and then is not involved in human affairs. According to the Bible, he is all knowing, and all powerful, despite the fact that you cant be all powerful and all knowing at the same time.
EDIT-Maybe it was Kusher?
Hitchens savages his immorality in this video.
