συνίουσιν: [10 verses](3rd pl fut ind act) "Understand" is from syniemi which means "to bring together" or "to set together." It is also a metaphor for "perceive", "hear," and "understand" as we would say that we "put it all together" when figuring something out. -- The word translated as "understand" means "to bring together." It means "understand" in the same sense that we say "put it together" to mean "understand." This word is always translated as "understand" in the KJV translation. A number of other Greek words begin with the same prefix, and all mean some form for bringing things together, for calling a meeting or to gather a crop.
