A.T. Robertson Commentary Luke 7:32

"They are like unto children that sit in the marketplace, and call one to another; who say, We piped unto you, and ye did not dance; we wailed, and ye did not weep." — Luke 7:32 (ASV)

And ye did not weep (κα ουκ εκλαυσατε). Here Mt 1:17 has "and ye did not mourn (or beat your breast, ουκ εκοψασθε). They all did it at funerals. These children would not play wedding or funeral.
