meek (adj.)

late 12c., mēk, "gentle or mild of temper; forbearing under injury or annoyance; humble, unassuming;" of a woman, "modest," from a Scandinavian source such as Old Norse mjukr "soft, pliant, gentle," from Proto-Germanic *meukaz (source also of Gothic muka-modei "humility," Dutch muik "soft"), a word of uncertain origin, perhaps from PIE *meug- "slippery, slimy." In the Bible, it translates Latin mansuetus from Vulgate (for which see mansuetude). Sense of "submissive, obedient, docile" is from c. 1300.

"those who are meek," c. 1200, from meek (adj.).
