It happened as they came, when David returned from the slaughter of the Philistine, that the women came out of all the cities of Israel, singing and dancing, to meet king Saul, with tambourines, with joy, and with instruments of music.
We are well aware that some very able commentators take this paragraph as a record of what happened immediately after David slew Goliath; but it appears to this writer that there are substantial objections to that viewpoint.  Not even the enthusiastic women could have referred to the victory over one man as his slaying his "ten thousands."  The most likely occurrence of this celebration was at the end of the whole military campaign, the temporary end of the war.
