Parallel
Isaiah 48:18
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ εἰ ἤκουσας τῶν ἐντολῶν μου ἐγένετο ἂν ὡσεὶ ποταμὸς ἡ εἰρήνη σου καὶ ἡ δικαιοσύνη σου ὡς κῦμα θαλάσσης
If only you had paid attention to My commandments, your peace would have been like a river, and your righteousness like waves of the sea.
