a question on subjunctive

[DavidP83]

Hello,

In Hermas Sheperd (Vision I), we find the following verse "διαβὰς οὖν τὸν ποταμὸν ἐκεῖνον ἦλθον εἰς τὰ ὁμαλά, καὶ τιθῶ τὰ γόνατα καὶ ἠρξάμην προσεύχεσθαι τῷ κυρίῳ καὶ ἐξομολογεῖσθαί μου τὰς ἁμαρτίας".

Could you please explain to me the meaning of the subjunctive for "τιθῶ τὰ γόνατα" / i kneeled down while the rest of the verse is at the indicative mood?

Thank you very much

It's a 1st sg. pres. act. indicative. See BDAG, which opens its entry as:

τίθημι (Hom.+) and its by-form τιθέω (Hv 1, 1, 3 and 2, 1, 2 as historical present; B-D-F §321; s. Rob. 318)
