《礼记·王制》
天子将出征，先祭祀上帝、社稷、宗庙。开战前在阵地上祭祀造军法的人，以壮军威。
天子将出征，类乎上帝，宜乎社，造乎祢，祃于所征之地。
Before going to war, the monarch would first offer sacrifices to the sovereign deity, the God of the Soil and Grain, and the ancestral temple. Before battle, he would offer sacrifices to the figure who had created the military law, so that the troops’ martial valor would be enhanced.
