Judges 3:2

3:2 He left those nations simply because he wanted to teach the subsequent generations of Israelites, who had not experienced the earlier battles, how to conduct holy war. ¹ 

Judges 13:4

13:4 Now be careful! Do not drink wine or beer, and do not eat any food that will make you ritually unclean. ² 

[3:2]  ¹ tn The Hebrew syntax of v. 2 is difficult. The Hebrew text reads literally, “only in order that the generations of the Israelites might know, to teach them war – only those who formerly did not know them.”

[13:4]  ² tn Heb “eat anything unclean.” Certain foods were regarded as ritually “unclean” (see Lev 11). Eating such food made one ritually “contaminated.”
