Now when He was in Jerusalem at the Passover, during the feast, many believed in His name when they saw the signs which He did. 24 But Jesus did not commit Himself to them, because He knew all men, 25 and had no need that anyone should testify of man, for He knew what was in man. — John 2:23-25.
“believed in His name” (v.23). — In biblical times the “name” summed up a person’s character, activity, and place in God’s purpose. The faith of those mentioned here remained superficial because they came to it only because “they saw the signs”. For that reason, Jesus “did not commit himself to them” (v. 24).
“did not commit Himself to them…He knew what was in man” (vv.24-25). — Although Jesus did not exercise divine omniscience in the days of His flesh (11:34; Mark 13:32), He often displayed supernatural knowledge, important for His redemptive work, that indicated the divine endorsement of His claims and mission (1:48; 9:4; 17:27; Mark 11:2–4; 14:13–16).
