'Breasts' in the Bible

and say ‘We piped the flute for you [playing wedding], and you did not dance; we wailed sad dirges [playing funeral], and you did not mourn and cry aloud.’

And at that time the sign of the Son of Man [coming in His glory] will appear in the sky, and then all the tribes of the earth [and especially Israel] will mourn [regretting their rebellion and rejection of the Messiah], and they will see the Son of Man coming on the clouds of heaven with power and great glory [in brilliance and splendor].
