Lip
Lips as a Symbol for Speech and Language
In the Bible, lips frequently stand as a metaphor for speech itself. Just as English uses 'tongue' to mean language, Hebrew and Greek writers used 'lips' to represent the act of speaking. Common biblical expressions include 'the utterance of the lips' (Numbers 30:6, 8), 'to open the lips' (Job 32:20), and 'to proceed out of the lips' (Numbers 30:12). These phrases convey the spoken word in all its forms, from solemn vows to everyday conversation.
The connection between lips and language is made explicit at the Tower of Babel narrative, where God confused the 'lip' (language) of all the earth (Genesis 11:1, 7). This usage demonstrates that in Hebrew thought, the lips were not merely a physical organ but represented the entire capacity for meaningful communication.
The Moral Character of Lips
The book of Proverbs is especially rich in attributing moral qualities to the lips. Scripture speaks of 'lying lips' (Proverbs 12:22; Psalm 31:18), 'perverse lips' (Proverbs 4:24), 'flattering lips' (Psalm 12:2-3; Proverbs 7:21), 'wicked lips' (Proverbs 17:4), and 'righteous lips' (Proverbs 16:13). Each designation reveals how the Bible connects outward speech with inward character.
The contrast between true and false speech is a central concern. Proverbs 12:19 declares, 'The lip of truth shall be established forever, but a lying tongue is but for a moment.' This pairing of lips and tongue in parallel structure reinforces the idea that what comes from a person's mouth reveals the condition of their heart.
Lips and Worship
The lips play a significant role in the Bible's theology of worship. The 'fruit of the lips' in Isaiah 57:19 and Hebrews 13:15 refers to praise and thanksgiving offered to God. Hosea 14:2 speaks of 'the calves of our lips,' using sacrificial language to describe verbal praise as an offering to the Lord.
Yet the prophets also warned against worship that was merely on the lips without genuine devotion. Isaiah 29:13 contains one of the most pointed critiques: 'This people draw near with their mouth and honor me with their lips, but their hearts are far from me.' Jesus quoted this very passage when confronting the Pharisees about their superficial piety (Matthew 15:8), establishing that God desires worship that flows from the heart, not just the lips.
Unclean Lips and Divine Cleansing
Isaiah's temple vision provides one of the most memorable uses of lip imagery in all of Scripture. When the prophet saw the Lord seated on His throne, surrounded by seraphim crying 'Holy, holy, holy,' his immediate response was, 'Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips' (Isaiah 6:5). The seraph's act of touching Isaiah's lips with a burning coal to purify them (Isaiah 6:6-7) dramatically illustrates how God cleanses human speech and prepares His servants for their calling.
Moses similarly described himself as having 'uncircumcised lips' (Exodus 6:12, 30), expressing his sense of inadequacy for the task of speaking before Pharaoh. This metaphor connects speech with the covenant concept of circumcision, suggesting that the lips, like the heart, need to be consecrated to God's purposes.
Covering the Lips: Mourning and Shame
A distinctive biblical practice involved covering the lips as an expression of mourning, submission, or shame. In the ancient Near East, a person in deep grief would cover their mouth with their hand or garment, signifying their inability to speak before God's visitation. Lepers were required to cover their lips and cry 'Unclean, unclean!' as a warning to others (Leviticus 13:45).
God specifically forbade Ezekiel from this mourning gesture when Jerusalem fell, instructing him not to cover his lips in the customary way (Ezekiel 24:17, 22). This prohibition served as a prophetic sign that Israel's destruction was a just consequence of their own sin, not an occasion for conventional mourning. The prophet Micah also called upon false seers and diviners to cover their lips in shame when God refused to answer them (Micah 3:7).
Biblical Context
Lip imagery pervades the Bible, appearing most frequently in Psalms, Proverbs, and the prophets. Key passages include the Tower of Babel (Genesis 11:1, 7), Moses' complaint about uncircumcised lips (Exodus 6:12), the cleansing of Isaiah's lips (Isaiah 6:5-7), the leper's covered lips (Leviticus 13:45), Ezekiel's mourning prohibition (Ezekiel 24:17), and Jesus' quotation of Isaiah 29:13 (Matthew 15:8). Proverbs contains the densest concentration of lip references, addressing lying, flattering, righteous, and perverse lips.
Theological Significance
The biblical treatment of lips teaches that human speech carries profound moral and spiritual weight. Words are not neutral — they can bless or curse, heal or destroy, worship truly or hypocritically. The cleansing of Isaiah's lips demonstrates that only God can purify human speech for divine service. Jesus' use of Isaiah 29:13 establishes that God judges the alignment between lips and heart. The 'fruit of the lips' as praise (Hebrews 13:15) shows that redeemed speech finds its highest purpose in worship.
Historical Background
In ancient Near Eastern cultures, the mouth and lips were considered the primary instruments of both blessing and cursing. Mesopotamian magical texts attributed great power to spoken words. The practice of covering the lips in mourning is attested in multiple ancient cultures and persisted in the Levant for centuries. In rabbinic tradition, the power of speech was considered one of humanity's most distinctive attributes, and extensive ethical teaching developed around the proper use of the tongue and lips.
