'Assembling' in the Bible

And Eli is very old, and hath heard all that his sons do to all Israel, and how that they lie with the women who are assembling at the opening of the tent of meeting,

But Samuel said, “What have you done?” And Saul said, “Because I saw that the people were scattering from me, and that you did not come within the appointed days, and that the Philistines were assembling at Michmash,

Saul replied, "When? I saw that the people were scattering from me, that you didn't come at the appointed time, and that the Philistines were assembling at Michmash. I thought, "The Philistines will come down against me at Gilgal but I've not sought the favor of the LORD,' so I forced myself to offer the burnt offering."
