οὗτος ἦλθεν (he/she/it came) . . . ἵνα μαρτυρήσῃ (he/she/it might bear witness) περὶ τοῦ φωτός, ἵνα πάντες πιστεύσωσιν (they might believe) δι ̓ αὐτοῦ. οὐκ ἦν ἐκεῖνος τὸ φῶς, αλλ᾿ ἵνα μαρτυρήσῃ περὶ τοῦ φωτός.

οὗτος ἦλθεν (he/she/it came) . . .

ἵνα μαρτυρήσῃ (he/she/it might bear witness) περὶ τοῦ φωτός,

ἵνα πάντες πιστεύσωσιν (they might believe) δι ̓ αὐτοῦ.

οὐκ ἦν ἐκεῖνος τὸ φῶς,

αλλ᾿ ἵνα μαρτυρήσῃ περὶ τοῦ φωτός.

This one came… in order that he might bear witness concerning the light, in order that all might believe through him. He was not the light, but he came in order that he might bear witness concerning the light.
