The phrase "stammering lips" appears in the context of biblical prophecy and is notably found in the book of Isaiah. This term is often associated with divine judgment and the communication of God's message through unexpected or foreign means.

Biblical Reference:

Isaiah 28:11-12 states, "Indeed, with mocking lips and foreign tongues, He will speak to this people to whom He has said: 'This is the place of rest, let the weary rest; this is the place of repose.' But they would not listen."

In this passage, the prophet Isaiah conveys a message from God to the people of Israel. The "stammering lips" and "foreign tongues" symbolize the method by which God will communicate His message to a disobedient and unrepentant nation. The Israelites, having rejected the clear and straightforward teachings of the prophets, would now hear God's word through the foreign invaders, the Assyrians, whose language would be unfamiliar and unintelligible to them. This serves as a form of judgment, highlighting the consequences of their refusal to heed God's call for repentance and rest.

Theological Significance:

The use of "stammering lips" underscores the theme of divine judgment and the reversal of expected norms. It illustrates how God can use unexpected means to fulfill His purposes and communicate His will. The foreign tongues represent a barrier to understanding, emphasizing the spiritual dullness and hard-heartedness of the people who have turned away from God.

This concept is further echoed in the New Testament, where the Apostle Paul references Isaiah's prophecy in 1 Corinthians 14:21 : "In the Law it is written: 'By strange tongues and foreign lips I will speak to this people, but even then they will not listen to Me, says the Lord.'" Paul uses this reference to address the issue of speaking in tongues within the Corinthian church, highlighting the importance of intelligibility and edification in the use of spiritual gifts.

Historical Context:

The historical backdrop of Isaiah's prophecy involves the impending Assyrian invasion. The Northern Kingdom of Israel faced the threat of conquest due to their persistent idolatry and failure to adhere to the covenant with Yahweh. The "stammering lips" of the Assyrians would serve as a tangible sign of God's judgment, as the Israelites would be subjected to a foreign power whose language they could not understand.

Application:

The imagery of "stammering lips" serves as a sobering reminder of the importance of listening to God's word and responding in obedience. It challenges believers to remain attentive to the clear teachings of Scripture and to seek understanding through the guidance of the Holy Spirit. The passage also encourages reflection on the ways God may use unexpected circumstances or people to convey His truth and call His people back to Himself.

In summary, the concept of "stammering lips" in the Bible highlights the themes of judgment, communication, and the necessity of spiritual receptivity. It serves as a poignant reminder of the consequences of ignoring God's voice and the diverse means through which He may choose to speak to His people.
