It is true that some of our understandings of God's immutibility and infinite attributes are derived some from the merging of some Greek philosophical concepts with biblical descriptions of God. I agree that some of these concepts are not so clearly spelled out as we tend to make it. However, much like the doctrine of the Trinity, while the Bible may not explicitly connect all the dots as cleanly and succinctly as our doctrinal statements may suggest, the concepts still are quite plainly inferred in the Scriptures.
For instance:
The NT clearly portrays God as the "one and only" and that there is none other besides him. There is none above him and he answers to no one. All things are by him and for him. He is the beginning and the end and nothing is hidden from his sight. So, while specific terms like omniscience may not be explicitly spelled out in philosophical detail, the narratives and self revelations God gives of himself make these connections apparent.

Tell us what is to come hereafter, that we may know that you are gods; do good, or do harm, that we may be dismayed and terrified. Behold, you are nothing, and your work is less than nothing; an abomination is he who chooses you. I stirred up one from the north, and he has come, from the rising of the sun, and he shall call upon my name; he shall trample on rulers as on mortar, as the potter treads clay.

This is just a sampling of verses of which we draw concepts like the immutability, eternal nature, omniscience and omnipotence of God. Thus, all point to his infinite qualities and show that God is not subject to other forces. He is not dependent on other things for life. He is not constrained by weakness, time or lack of understanding. He does all he wants and all he does is good and perfect. There is none other like him or comparable to him that he is in competition or rivaled by another. He alone as absolute power and authority in all things.
