Verse 3: And the children of Israel cried unto the LORD: for he had nine hundred (Judg. 1:19) chariots of iron; and twenty years (Judg. 5:8; Ps. 106:42) he mightily oppressed the children of Israel.
[He had exceedingly oppressed (similarly Munster, Tigurinus), בְּחָזְקָה] In strength (Montanus, similarly Pagnine); in rigor (Jonathan); with violence (Syriac, Arabic, Junius and Tremellius); imperiously (Septuagint); τυραννικῶς/ tyrannically (Drusius).
He mightily oppressed: More than the former tyrants; partly from his malice and hatred against the Israelites; and principally from God’s just judgment, the growing punishment being most suitable to their aggravated wickedness.
