It parses every Greek word in the New Testament and LXX. It also gives you different definitions and word occurences.

www.blueletterbible.com is good as well.

George, please transliterate this psalm, I want to read it properly in Greek: Ψαλμὸς τῷ Δαυΐδ. - ΚΥΡΙΟΣ ποιμαίνει με καὶ οὐδέν με ὑστερήσει. 2 εἰς τόπον χλόης, ἐκεῖ με κατεσκήνωσεν, ἐπὶ ὕδατος ἀναπαύσεως ἐξέθρεψέ με, 3 τὴν ψυχήν μου ἐπέστρεψεν. ὡδήγησέ με ἐπὶ τρίβους δικαιοσύνης ἕνεκεν τοῦ ὀνόματος αὐτοῦ. 4 ἐὰν γὰρ καὶ πορευθῶ ἐν μέσῳ σκιᾶς θανάτου, οὐ φοβηθήσομαι κακά, ὅτι σὺ μετ᾿ ἐμοῦ εἶ· ἡ ράβδος σου καὶ ἡ βακτηρία σου, αὗταί με παρεκάλεσαν. 5 ἡτοίμασας ἐνώπιόν μου τράπεζαν, ἐξεναντίας τῶν θλιβόντων με· ἐλίπανας ἐν ἐλαίῳ τὴν κεφαλήν μου, καὶ τὸ ποτήριόν σου μεθύσκον με ὡσεὶ κράτιστον. 6 καὶ τὸ ἔλεός σου καταδιώξει με πάσας τὰς ἡμέρας τῆς ζωῆς μου, καὶ τὸ κατοικεῖν με ἐν οἴκῳ Κυρίου εἰς μακρότητα ἡμερῶν. Thank you.
