Isaiah 65:3 Commentary: Sacrificing on Bricks, Open Defiance Study

Isaiah 65 opens a divine response to the prayer of the community in chapters 63, 64. The Lord distinguishes between those who seek him and a “rebellious people” who walk their own way. Verse 3 supplies evidence for the indictment: the specific, outward forms of their rebellion.

Gardens were a hallmark of ancient Near Eastern worship. The Canaanites and others often set up altars and sacred poles in groves or planted gardens, believing those shaded places housed deities or spirits. Israel was told to tear down such sites (Deuteronomy 12:2, 3). To sacrifice in a garden was therefore not just a different location, it was a deliberate return to the worship culture God had expelled from the land.

‘Burning incense on the bricks’ carries two possible backgrounds, both reflecting disobedience. First, altars made of baked brick stood in sharp contrast to the simple unhewn-stone or earth altars God prescribed (Exodus 20:24, 25). Bricks could be inscribed with idolatrous symbols more easily than stone, as Keil and Delitzsch point out, and baked brick was a technology associated with Babylon (the tower of Babel, Genesis 11:3). Second, the flat roofs of houses, paved with brick or tile, were used for offerings to the sun and other celestial bodies (2 Kings 23:12; Jeremiah 19:13; Zephaniah 1:5). Either way, perhaps both, the worshippers chose a material and a method that the Law forbade.

The surrounding verses (vv. 4, 5) add more offenses: consulting the dead, eating unclean food, and a self-righteous separation that claimed holiness while practicing abominations. Verse 7 will later say these are ‘your own iniquities and the iniquities of your fathers.’ For the original audience, the verse likely recalled the last decades before the Babylonian exile, when such syncretism was rampant. For the post-exilic community reading it, the warning stood: the same pattern of defiant worship could bring fresh judgment.

The supplied sources note no significant textual variants for Isaiah 65:3. The Masoretic Text is stable across the main manuscripts, with only spelling differences in the lexical forms. The translations consulted handle the Hebrew uniformly, with minor variation only in how ‘bricks’ is rendered (bricks, tiles, altars of brick).

Isaiah 65 as a whole was pivotal in the New Testament, Paul quotes verses 1, 2 in Romans 10:20, 21 to argue that Gentiles received the gospel while Israel remained disobedient. Though verse 3 is not directly cited, early Christian interpretation read the whole chapter as a portrait of Jewish rejection and Gentile inclusion. Jerome, writing in the fourth century, connected the ‘brick’ altars to the brickmaking of Egypt and Babylon, seeing the idolaters as those who adopt the worship styles of their captors. Matthew Henry and Wesley followed this line, emphasizing the impudence of sinning ‘to God’s face.’ In more recent centuries, commentators have debated the historical referent, whether this is a picture of pre-exilic Judah or a prophetic composite, but all have agreed that the verse warns against syncretistic worship that looks religious on the outside but is rebellion at its core.

Three-point outline

1. The Brazenness of Sin, “To my face continually.” The people provoked God openly, as if daring him to act. Sin that hides itself is grievous; sin committed in plain sight is a doubled offense.
2. The Specifics of Disobedience, Gardens and bricks: the wrong place and the wrong material. God cares about the “what” and the “how” of worship, not just the heart vague of intention.
3. The Silence That Ends, God’s spread-out hands (v.2) will not last forever. Verse 6 warns: “I will not keep silence, but will repay.” Persistent provocation meets divine response.

Five-point outline

1. The people: God’s own nation, called to be holy.
2. The action: provoking, sacrificing, burning incense, religious acts turned rebellious.
3. The attitude: “to my face”, no shame, no fear, no concealment.
4. The duration: “continually” (tāmîd), it was their consistent pattern, not a lapse.
5. The judgment: God will repay (v.6), because he cannot tolerate open defiance indefinitely.

Illustration hooks

• Someone speeding past a police car parked on the shoulder, making eye contact as they pass. That added layer of “right in front of you” changes the offense.
• A child told to use crayons for a coloring project but deliberately using markers instead, then showing the work to the parent as if proud of the defiance.
• An employee instructed to follow a specific safety protocol but instead doing things the “fast way” in full view of the supervisor, undoing the protection the protocol was meant to provide.

Questions your congregation is asking

• Does God really care about the details of how we worship, or is a sincere heart enough?
• How can I tell when I am “provoking” God rather than pleasing him, especially when my actions look religious on the surface?
• What modern “gardens” and “bricks” do Christians substitute for God’s commands today?

This verse paints a picture of worship that looks busy, sacrifices, incense, but is actually rebellion. The people are doing the acts, but in places and with materials God forbade. Use these questions to explore what commands we might be tempted to bend while still calling it worship.

Discussion questions

1. Read Isaiah 65:1, 7. What is the emotional tone of God’s complaint? How does verse 3 fit into the larger argument?
2. Why does God take the location of worship so seriously? What do “gardens” represent in the Old Testament (see also Deuteronomy 12:2, 3)?
3. The Hebrew word for “bricks” (l e vēnīm) can mean tile or brick. What difference does it make whether the incense was burned on rooftop tiles or on altars made of brick? Why does either seem to anger God?
4. Barnes and Clarke both note that “to my face” means there was no attempt to hide the sin. In what ways might Christians today commit sin openly, without even feeling the need to conceal it?
5. The phrase “continually” (tāmîd) suggests a pattern, not a fall. How does habitual sin differ from a single failure in its effect on our relationship with God?
6. Exodus 20:24, 25 and Leviticus 17:5 show God laying down specific rules for altars and sacrifices. Why might God be so concrete about worship rather than leaving it up to individual preference?
7. If someone in your group said, “I just want to worship God my way,” how would you respond in light of this verse? What freedoms does Scripture give, and where does it draw lines?
