These are those who with nashim (women) are not tameh (unclean, defiled), bochrim ki betullim they are, for these are the ones following the SEH (Lamb), wherever he goes. These chasidim had the Geulah price paid for their redemption, the ones having been purchased from Bnei Adam as the bikkurim (firstfruits) to Hashem and to the SEH (Lamb).
