Parallel
Matthew 12:40
Patriarchal Greek New Testament (1904) · Berean Standard Bible
ὥσπερ γὰρ ἐγένετο Ἰωνᾶς ὁ προφήτης ἐν τῇ κοιλίᾳ τοῦ κήτους τρεῖς ἡμέρας καὶ τρεῖς νύκτας, οὕτως ἔσται [καὶ] ὁ υἱὸς τοῦ ἀνθρώπου ἐν τῇ καρδίᾳ τῆς γῆς τρεῖς ἡμέρας καὶ τρεῖς νύκτας.
For as Jonah was three days and three nights in the belly of the great fish, so the Son of Man will be three days and three nights in the heart of the earth.
