Strong’s Entry

g4909

Gloss: suneudokeo (soon-yoo-dok-eh’-o) v.1. to think well of in common, i.e. assent to, feel gratified with[from G4862 and G2106]KJV: allow, assent, be pleased, have pleasure Root(s): G4862, G2106 

συνευδοκέω represents a profound concept of shared approval or consent. As a compound word, it combines σύν (together), εὖ (well), and δοκέω (to think), creating a term that describes active agreement or approval of actions. In its first New Testament appearance in Luke 11:48, Jesus uses it to describe the complicity of those who approve of their ancestors’ persecution of prophets. The early church understood this term as expressing moral responsibility through agreement or approval, even without direct participation. Today, this word continues to challenge believers about our responsibility in tacitly approving or consenting to wrongdoing.
