"Wind", at the end of the second line cited refers to the weather phenomenon and should rhyme with "friend" in its normal pronunciation. That would make it not rhyme with "mind" or "find" in the preceeding and following lines. But to make it rhyme, it is sometimes pronounced to rhyme with those other two words. Than makes "wind" SOUND like an entirely different word, a word for what a crooked river does, or once upon a time a word for what one did with one's watch to keep it running, a meaning likely lost on today's youth who grew up in the world of first self-winding watches and then battery operated and mostly didgital watches. In any event, the actual word in the song is the still common word "wind", the weather phenomenon, but to make it rhyme it is often pronounced like its homograph, the becoming-less-common word "wind" possibly more remembered today as the root of "rewind".

LOOKED is always pronounced as "look-ed" in this traditional Christmas hymn.
