1: μή
►
(Strong's #3361 — particle — me — may )

a negative particle, often used as a conjunction, is frequently translated "lest," e.g., Mark 13:36 (in ver. 5, RV, "that no," for AV, "lest"); Acts 13:40; 23:10 .

2: ἵνα μή
►
(Strong's #3363 — Conjunction — hina me — hin'-ah may )

"in order that not," is rendered "lest," e.g., in Matthew 17:27; in some instances the RV renders the phrase "that ... not," e.g., Luke 8:12 , or "that ... no," 1—Corinthians 9:12 (AV, "lest").

3: μήποτε
►
(Strong's #3379 — Conjunction — mepote | me pote — may'-pot-eh, may pot'-eh )

denotes "lest ever, lest perhaps, lest at any time," e.g., Matthew 4:6; "lest haply," Matthew 7:6 , RV (AV, "lest"), and in Matthew 13:15 (AV, "lest at any time"); in Matthew 25:9 , RV, "peradventure" (AV, "lest"). The RV does not translate this simply by "lest," as in the AV; see further, e.g., in Matthew 27:64; Mark 14:2; Luke 12:58; the addition of pote requires the fuller rendering.

Luke 14:29

(Strong's #3381 — Conjunction — mepos | me pos — may'-poce, may poce )

used as a conjunction, denotes "lest somehow, lest haply, lest by any means," e.g., 2—Corinthians 2:7 , RV, "lest by any means" (AV, "lest perhaps"); so 2—Corinthians 12:20 (twice); Galatians 4:11 (AV, "lest"); in 1—Thessalonians 3:5 (AV, "lest by some means").
