Brief Overview of πλατύνω (Strong’s G4115: platynō)

Strong’s G4115: A verb meaning to make broad, widen, or enlarge. From πλατύς (platys), “broad.” In ancient Greek, it described physical expansion. In New Testament usage, it appears both literally regarding religious accessories and metaphorically for spiritual/emotional enlargement.

U- Unveiling the Word

πλατύνω carries both physical and metaphorical significance in Scripture. In Matthew, Jesus criticizes the Pharisees’ practice of enlarging their phylacteries for show, while Paul uses it to describe spiritual and emotional expansion of the heart. The early church understood this term as representing both external religious display and genuine internal spiritual growth. Today, it continues to challenge us about authentic faith versus outward religious demonstration.
