John 5:42

ἀλ ἔγνωκα ὑμᾶς ὅτι τὴν ἀγάπην τοῦ θεοῦ οὐκ ἔχετε ἐν ἑαυτοῖς

But I know you all that you all do not have the love of God


 * ὑμᾶς - Jesus is addressing a group, hence 2P plural, "you all"
 * ἔγνωκα - Perfect 1P sg. γν often indicates it comes from γινώσκω (I know). κ often indicates perfekt.
 * τὴν ἀγάπην τοῦ θεοῦ - objective genitive or subjective genitive?
 * τὴν ἀγάπην gives the verbal idea, love
 * subjective genitive means the genitive τοῦ θεοῦ is the subject, the one doing the loving. Easily rememebered by attaching 's to the gloss. God's love.
 * objective genitive means the the genitive τοῦ θεοῦ is the object, that which receives the loving, love of God, love for God.
 * From context, it implies objective, meaning the "you all" do not have love for God.
