Such knowledge is too wonderful for me - literally, "Wonderful knowledge away from me," or, more than I can comprehend. It is beyond my reach; it surpasses all my powers to comprehend it.

It is high, I cannot attain unto it - It is so exalted that I cannot grasp it; I cannot understand how it can be.

Such knowledge is too wonderful - I think, with Kennicott, that פלאיה דעת pelaiah daath should be read פלאי הדעת peli haddaath, "This knowledge," ממני mimmenni, "is beyond or above me." This change is made by taking the ה he from the end of פלאיה pelaiah, which is really no word, and joining it with דעת daath; which, by giving it an article, makes it demonstrative, הדעת haddaath, "This knowledge." This kind of knowledye, God's knowledge, that takes in all things, and their reasons, essences, tendencies, and issues, is far beyond me.

Such knowledge is too wonderful for me,.... Meaning either the knowledge of himself, such as God had of him, which was vastly superior to what he had of himself; and especially the knowledge of other persons and things, whether visible or invisible, in heaven, earth, or hell; things past, present, and to come; or else the manner in which God knew all this was amazing to him, and quite impenetrable by him; that he did know him, his thoughts, his words and actions, and so those of all others, was easy of belief; but how he should know all this was past his conception, and struck him with the profoundest admiration;

it is high; sublime, out of his reach, beyond his comprehension;

I cannot attain unto it; neither to such knowledge, nor to comprehend what it is in God; and how he should have it, and in what manner he exercises it. Kimchi, Jarchi, and Aben Ezra, connect the words with the following, as if the matter of his wonder and astonishment was the omnipresence of God, or where he should find a place to flee from him.

Such knowledge is too wonderful for me; it is high, I cannot attain unto it.

139:6 I cannot - Apprehend in what manner thou dost so presently know all things.

139:1-6 God has perfect knowledge of us, and all our thoughts and actions are open before him. It is more profitable to meditate on Divine truths, applying them to our own cases, and with hearts lifted to God in prayer, than with a curious or disputing frame of mind. That God knows all things, is omniscient; that he is every where, is omnipresent; are truths acknowledged by all, yet they are seldom rightly believed in by mankind. God takes strict notice of every step we take, every right step and every by step. He knows what rule we walk by, what end we walk toward, what company we walk with. When I am withdrawn from all company, thou knowest what I have in my heart. There is not a vain word, not a good word, but thou knowest from what thought it came, and with what design it was uttered. Wherever we are, we are under the eye and hand of God. We cannot by searching find how God searches us out; nor do we know how we are known. Such thoughts should restrain us from sin.
