Was there Snow in Bethlehem?

According to Google snow was recorded in Jerusalem in December 1990, but none since then. So what do we make of ‘Snow had fallen, snow on snow.’

‘We three kings of Orient are bringing gifts, we travel afar.’ No-where in the Bible does it say there were three kings, just three gifts.

‘The cattle were lowing, the baby awakes , but little Lord Jesus no crying He makes.’ No crying with all that straw sticking in Him! I’m sue that even Jesus, bawled His head off at times.

But hymn writers have to get their metres and rhymes right. The most important thing is that He was born, died for our sins and rose again.
