Corresponding Greek / Hebrew Entries: The concept of speaking in different tongues or languages can be related to several Hebrew terms that describe language and speech, such as:
• Strong's Hebrew 3937: לָשׁוֹן (lashon) • meaning "tongue" or "language."
• Strong's Hebrew 8193: שָׂפָה (saphah) • meaning "lip" or "language."
These Hebrew terms are often used in the Old Testament to describe the diversity of languages among nations and the communication of God's message through various tongues.

Usage: The word ἑτερόγλωσσος appears in the New Testament in contexts that discuss the diversity of languages, particularly in relation to the gift of tongues and the spread of the Gospel to different peoples.

Context: The term ἑτερόγλωσσος is notably used in the New Testament to describe the phenomenon of speaking in tongues, a spiritual gift that enabled early Christians to speak in languages they had not learned. This gift served as a sign to unbelievers and facilitated the spread of the Gospel across linguistic barriers. In 1 Corinthians 14:21, the Apostle Paul references the concept of speaking in different tongues, quoting from the Old Testament to illustrate the point that God would speak to His people through those of other tongues and lips. This passage highlights the fulfillment of prophecy and the inclusivity of the Gospel message, reaching beyond the Jewish community to encompass all nations and languages. The use of ἑτερόγλωσσος underscores the miraculous nature of this gift and its role in the early church's mission.
