Mark 1:12

Καὶ εὐθὺς τὸ πνεῦμα αὐτὸν ἐκβάλλει εἰς τὴν ἔρημον

And immediately the spirit cast him into the wilderness


 * εὐθὺς - immediately, very common especially in the first few chapters of Mark
 * ἐκβάλλει - cast out, throw etc. Is in the historical present.
 * τὴν ἔρημον - the wilderness. This is an adjective and here it is feminine. What is the gender agreeing with? Actually in the NT, the adjective wilderness occurs both in masc. and fem. genders, so it is not a matter of convention. Perhaps in this case Mark means the wilderness of Judea (feminine word in Greek). Judea is not mentioned explicitly in Mark but in Matthew it is.
