Purify/Purified

is,

To make (or made)
clean, and clear;
without spot or corruption;
free from moral defilement.

... Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ; Who gave Himself for us, that He might redeem us from all iniquity, and purify unto Himself a peculiar people,
zealous
of  good works.

Titus  
2:11-14
