The bible says to pay your taxes.. Isn?t military service a form of tax? When the iserlites wanted a king, didn?t Samuel name all of the taxes that they would be expected to pay? One of witch was military service..
1 Samuel 8 MSG
11 He said, "This is the way the kind of king you're talking about operates. He'll take your sons and make soldiers of them--chariotry, cavalry, infantry, 12 regimented in battalions and squadrons. He'll put some to forced labor on his farms, plowing and harvesting, and others to making either weapons of war or chariots in which he can ride in luxury. 13 He'll put your daughters to work as beauticians and waitresses and cooks. 14 He'll conscript your best fields, vineyards, and orchards and hand them over to his special friends. 15 He'll tax your harvests and vintage to support his extensive bureaucracy. 16 Your prize workers and best animals he'll take for his own use. 17 He'll lay a tax on your flocks and you'll end up no better than slaves..
