Joshua 10:21 New English Translation

²¹Then the whole army safely returned to Joshua at the camp in Makkedah.^[a] No one^[b] dared threaten the Israelites.^[c]

Joshua 10:21 tn Heb “all the people returned to the camp, to Joshua [at] Makkedah [in] peace.”
Joshua 10:21 tc Heb “No man.” The lamed (ל) prefixed to אִישׁ (ʾish, “man”) is probably dittographic (note the immediately preceding יִשְׂרָאֵל [yisraʾel] which ends in lamed, ל); cf. the LXX.
Joshua 10:21 tn Heb “no man sharpened [or perhaps, “pointed”] his tongue against the sons of Israel.” Cf. NEB “not a man of the Israelites suffered so much as a scratch on his tongue,” which understands “sharpened” as “scratched” (referring to a minor wound). Most modern translations understand the Hebrew expression “sharpened his tongue” figuratively for opposition or threats against the Israelites.
