Judges 3:4
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ ἐγένετο ὥστε πειράσαι ἐν αὐτοῖς τὸν Ισραηλ γνῶναι εἰ ἀκούσονται τὰς ἐντολὰς κυρίου ἃς ἐνετείλατο τοῖς πατράσιν αὐτῶν ἐν χειρὶ Μωυσῆ
These nations were left to test the Israelites, to find out whether they would keep the commandments of the LORD, which He had given their fathers through Moses.
