Matthew 3:16a

βαπτισθεὶς δὲ ὁ Ἰησοῦς εὐθὺς ἀνέβη ἀπὸ τοῦ ὕδατος

And being baptised, Jesus immediately rose up out of the water


 * βαπτισθεὶς - nice classic example of a participle. Aorist passive participle nominative sg. masculine.
 * aorist because the baptism is a done deal, seen as a whole, perfective aspect
 * passive because the action is done to the subject Jesus
 * nominative sg. masc. all to agree with the subject Jesus
 * from βαπτίζω - note how the θ causes the ζ to change to σ.
 * δὲ - postpositive
 * εὐθὺς - immediately, commonly found in Mark
 * ἀνέβη - aorist form, the aorist is default tense for narratives. Perhaps imperfect could work here too? Because this action is setting the scene for what happens next.... as in Jesus was rising out of the water when....
 * ἀπὸ τοῦ ὕδατος - out of the water. Notice the ἀπὸ takes a genitive. ὕδατος is genitive sg. of neuter ὕδωρ.
