'Rejoice' in the Bible

so then, as it is written [in Scripture], “He who boasts and glories, let him boast and glory in the Lord.”

and those who weep, as though they did not weep; and those who rejoice, as though they did not rejoice; and those who buy, as though they did not possess [anything];

It does not rejoice at injustice, but rejoices with the truth [when right and truth prevail].
