475. The negative of the Subjunctive both in principal and in subordinate clauses is mh, except in clauses introduced by the conjunction mh,, lest. In these the negative is ouv. Concerning ouv mh, with the Subjunctive see 487, 488. HA. 1019, 1033; G. 1610
1 John 3:18; mh. avgapw/men lo,gw|, let us not love in word.

Heb. 4:7; mh. sklhru,nhte ta.j kardi,aj u`mw/n, harden not your hearts.

2 Cor. 12:20; fobou/mai ga.r mh, pwj evlqw.n ouvc oi[ouj qe,lw eu[rw u`ma/j, for I fear, lest by any means, when I come, I should find you not such as I would. See also Acts 20:16; Rom. 10:15; 1 Cor. 2:5.

REM. 1. In Matt. 25:9 a Subjunctive after the conjunction mh, is negatived by ouv (WH. margin), or, according to other MSS., followed by WH. (text) by the strong negative ouv mh,.

REM. 2. In Rom. 5:11 ouv mo,non limits a verb understood which is probably to be taken as a Subjunctive. Cf. 479, 481.

476. In classical Greek, ouv is used with the Potential Optative; mh, with the Optative of Wishing. In the New Testament, no instance of a negatived Potential Optative occurs. With the Optative of Wishing mh, is used as in classical Greek. HA. 1020; G. 1608.

Gal. 6:14; evmoi. de. mh. ge,noito kauca/sqai, but far be it from me to glory. See also Mark 11:14; Rom. 3:4, 6, 31, etc.
477. In classical Greek, the Optative in subordinate clauses takes mh. as its negative except in indirect discourse and after mh. lest. HA. 1021, 1022; G. 1610.

In the New Testament, no instance of a negatived Optative in a subordinate clause occurs.

478. The negative of the Imperative is mh. HA. 1019; G. 1610.

This rule holds in the New Testament with very rare exceptions.

Luke 12:11; mh. merimnh,shte pw/j h' ti, avpologh,shsqe, be not anxious how or what ye shall answer. See also under 165.
479. Of the apparent exceptions to the rule stated above (478), some are to be explained as parenthetic non-imperative phrases in the midst of imperative sentences. So, clearly, in 1 Cor. 5:10, [I meant] not [that you should have no company] at all, with the fornicators of this world, etc. So also 2 Tim. 2:14, that they strive not about words, [a thing which is] profitable for nothing. The use of ouvc rather than mh, in 1 Pet. 3:3 seems to indicate that the following words, o`  . . . ko,smoj, are excluded from the injunction rather than included in a prohibition. In 1 Pet. 2:18 ouv mo,non occurs, perhaps as a fixed phrase, after a participle with Imperative of the verb ei=nai understood. On the other hand, it is noticeable that elsewhere limitations of the Imperative when negatived regularly take mh,. Thus mh, mo,non occurs in John 18:9; Phil. 2:12; Jas. 1:22. Cf. 481.
