'Exultingly' in the Bible

Who rejoice even exultingly and are glad when they find the grave? --

Rejoice not, Israel, exultingly, as the peoples; for thou hast gone a whoring from thy God, thou hast loved harlot's hire upon every corn-floor.

Not only that, but we also rejoice in God [rejoicing in His love and perfection] through our Lord Jesus Christ, through whom we have now received and enjoy our reconciliation [with God].
