What does Deuteronomy 20:3 mean?

and shall say unto them, Hear, O Israel, ye draw nigh this day unto battle against your enemies: let not your heart faint; fear not, nor tremble, neither be ye affrighted at them;

And shall say unto them, Hear, O Israel, ye approach this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be ye terrified because of them;

and shall say unto them, Hear, O Israel, ye draw nigh this day unto battle against your enemies: let not your heart faint; fear not, nor tremble, neither be ye affrighted at them;

Give ear, O Israel: today you are going forward to the fight; let your heart be strong; do not let uncontrolled fear overcome you because of those who are against you;

and said unto them, Hear, Israel, ye are drawing near to-day to battle against your enemies, let not your hearts be tender, fear not, nor make haste, nor be terrified at their presence,

Hear, O Israel, you join battle this day against your enemies, let not your heart be dismayed, be not afraid, do not give back, fear ye them not:

and shall say unto them, Hear, Israel, ye are approaching this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be afraid of them;
