They have not known nor understood: for he hath shut their eyes, that they cannot see; [and] their hearts, that they cannot understand.

They do not comprehend or discern, for He has shut their eyes so they cannot see and closed their minds so they cannot understand.
They know not, neither do they consider: for he hath shut their eyes, that they cannot see; and their hearts, that they cannot understand.

Context
Isaiah 44:18 is situated within a section of the book (chapters 40-48) where the prophet Isaiah contrasts the power and uniqueness of the one true God with the futility and foolishness of idol worship. The verses immediately preceding this one (Isaiah 44:9-17) vividly describe the process of making an idol from wood – using part of the tree for fuel and part to carve a god. This verse then speaks to the spiritual state of those involved in such practices, explaining why they persist in such obvious folly. It highlights a profound lack of perception and understanding regarding the truth about God and the vanity of idols.

Linguistic Insights
The Hebrew words used are significant. "Known" (yada’) implies experiential knowledge, while "understood" (biyn) suggests discerning and comprehending. The phrase "he hath shut" uses the verb tach, which means to smear over, plaster, or shut up, indicating a deliberate covering or closing. The "eyes" (‘eynayim) are the organs of perception, and "hearts" (libbam - their heart, singular used collectively) refers to the inner person, the seat of intellect, will, and emotion. In Hebrew thought, the heart is crucial for understanding and moral decision-making. The blindness affects both outward perception and inner comprehension.
Reflection and Application
Isaiah 44:18 serves as a stark warning about the dangers of spiritual insensitivity. Whether through blatant idolatry or the worship of modern substitutes (wealth, power, self, ideas), focusing on created things instead of the Creator can lead to a state where one is genuinely unable to perceive spiritual reality. This verse reminds us that true understanding is not merely intellectual but requires a spiritual openness and a heart receptive to God. It underscores the need for God's grace to open our eyes and hearts, as only He can remove the spiritual blindness that prevents us from knowing and understanding His truth. We should pray for ourselves and others that God would "open their eyes" that they might see the truth of the gospel (Acts 26:18).
