Yes, you're right. The alpaca I have is very thick anyway, no good for a mask. I'll check the content of other family members' wardrobes to make sure their clothes aren't an abomination.
Deuteronomy 25:16 ~ full context available here
For all that do such things, and all that do unrighteously, are an abomination unto the LORD thy God.
God has been explaining what to do during battles, anyway eventually the guaranteed victory has been attained and God is right there with commands relating to how His people should conduct themselves once they move into territory formerly held by the wretched soldiers He's just driven out. Christians live in a new commonwealth under the dominion of Christ, redeemed from devils previously in charge. And like The Israelites we have God's Impeccable Standard to guide us. He never changes. What was right before is right today, unlike false creeds cooked up to say that abominations have become "lifestyle choices" and that virtues are now villainies of the first water.
God's opinion, considered by those standards, is serpents in your clothing biting you all over. The one thing He requires is obedience which, in the matter of masks, is covered by the fabric command still current and still right after all these years. God knows all about the virus He made and what we must do to be saved.
