Deuteronomy 20:3; Deuteronomy 20:8

3 "He shall say to them, 'Hear, O Israel, you are approaching the battle against your enemies today. Do not be fainthearted . Do not be afraid, or panic, or tremble before them,

8 "Then the officers shall speak further to the people and say, 'Who is the man that is afraid and fainthearted ? Let him depart and return to his house, so that he might not make his brothers' hearts melt like his heart.'
