Keep far from a false charge; do not bring death on those who are innocent and in the right, for I will not acquit the wrongdoer.
Distance yourself from a false matter - put distance between yourself and those who speak lies, and gossipers, since on this the text already warned: 'you must not carry false rumors' (Exodus 23:1) and then 'do not bring death on those who are innocent and in the right' (Ex. 23:7) because liars cause the killing of the ones in the right and of the innocent.

מדבר שקר תרחק, the Torah addresses the judge, telling him to stay clear of anything which could create the impression that he has dealings with something corrupt. Our sages enlarge on this, cautioning that the judge must be careful with all his utterances so that a liar cannot exploit his words for his own nefarious purposes. (Avot 1,9)

The Sages taught: From where is it derived that a judge should not engage in advocacy [saneigeron] for his own statements and devise various pretexts to justify his erroneous rulings? It is derived as the verse states: “Distance yourself from a false matter” (Exodus 23:7). And from where is it derived with regard to a judge that a student who is an ignoramus should not sit before him to discuss the proceedings? It is derived as the verse states: “Distance yourself from a false matter.” When an ignorant student engages in the proceedings, he is apt to cause the judge to err in judgment.
Apropos the previous statement, the Gemara cites an additional statement. And Rav Ḥisda says that Rabbi Yirmeya bar Abba says that four groups do not receive the Divine Presence: This pertains to the group of cynics, the group of liars, the group of flatterers, and the group of slanderers. This pertains to the group of cynics, as it is written: “He withdrew His hand with cynics” (Hosea 7:5), indicating that God distanced Himself from them. This pertains to the group of liars, as it is written: “He that speaks falsehoods shall not be established before My eyes” (Psalms 101:7). This pertains to the group of flatterers, as it is written: “That a flatterer shall not come before Him” (Job 13:16). This pertains to the group of slanderers, as it is stated: “For You are not a God who desires wickedness; evil shall not dwell with You” (Psalms 5:5), which means: You are righteous, and there will be no form of evil in Your dwelling.
You shall not steal; you shall not deal deceitfully or falsely with one another.
ולא תשקרו NEITHER SHALL YE LIE [ONE TO ANOTHER] — Since Scripture has stated (V. 22) “[If a soul sin… and deny unto his neighbour a charge or a deposit…] and sweareth falsely (לשקר)" that he shall pay the principal and shall add the fifth part more thereto, we have there mention only of the punishment he incurs; whence do we derive the prohibition to lie? From Scripture's statement here “ye shall not lie one to another”.
