This is the 2555th most frequent German word.
weine
"Weine" means "wines" (plural of "der Wein") or "cry" (1st-person singular or imperative of "weinen").
Here 'weine' is used incorrectly; the correct form should be 'weinten'. This demonstrates the typical error learners make in past tense conjugation.
Die Kinder weine vor Freude, als sie das Geschenk sahen.
The children cry with joy when they see the gift.
In this case, 'weine' is used as an imperative form addressing the second person singular to give the command 'Do not cry'.
Weine nicht, es wird alles gut!
Don't cry, everything will be alright!
Here, 'weine' is the first singular person present tense of the verb 'weinen', which means 'to cry'.
