{That desire to be under the law} (hoi hupo nomon thelontes
einai). "Under law" (no article), as in  3:23  4:4 , legalistic
system. Paul views them as on the point of surrender to legalism,
as "wanting" (	helontes) to do it ( 1:6  3:3  4:11,17 ). Paul
makes direct reference to these so disposed to "hear the law." He
makes a surprising turn, but a legitimate one for the legalists
by an allegorical use of Scripture.
