Two Prayers in Deuteronomy:

20. Moses asking to go over into Canaan (59 words; Deut 3:24-25). Unanswered because of sin (Deut 3:26; Num 20:12).

21. Moses for Israel to be spared (114 words; Deut 9:26-29). Answered because of intercession of Moses (Ex 32:11-14).

References to prayer (Deut 9:20,26), also what to pray for elders at murder trials (Deut 21:6-9) and what all Israel should pray after obedience to the law (Deut 26:5-15).
