alternation belongs indeed rather to the higher style, and even then it depends upon the view and intention of the speaker, whether he wishes the action, &c., to be regarded as the logical consequence of what has preceded, or as simply co-ordinate with it, and so in the same tense.
[c] 2. A succession of any number of other perfects consecutive may be co-ordinated with a perfect consecutive (cf. e.g. Ez 1413, Am 519, Ru 33, four perfects in each case, Is 87 five, Ex 66f. eight). It is true, however, of the perfect (as conversely of the imperfect, § 112 c), that as soon as the Wāw is separated by any intervening word from the verb to which it belongs, an imperfect necessarily takes the place of the perfect, e.g. Gn 1212 when the Egyptians shall see thee, they shall say (וְאָֽמְרוּ), This is his wife: and they will kill me (וְהָֽרְנוּ אֹתִי) but thee they will save alive (וְאֹתָךְ יְהַיּוּ).
[d] 2. The perfect consecutive, like the imperfect consecutive, always belongs to the period of time expressed by the preceding tense, or its equivalent, with which it is connected as the temporal or logical consequence. The particular cases may be classed under three heads: (a) the perfect consecutive in immediate dependence (see e), (b) in loose connexion (see x) with the preceding, and (c) the perfect consecutive at the beginning of the apodosis to other sentences, or their equivalents (see ff).
[e] 3. The perfect consecutive in immediate dependence on the preceding tense, or its equivalent, serves
(a) As a frequentative tense to express past actions, &c., i.e. actions repeatedly brought to a conclusion in the past, and follows tenses, or their equivalents, representing actions which have continued or been repeated in the past:
(α) After a simple imperfect, e.g. Gn 26 אֵד יַֽעֲלֶה there went up a mist (again and again) from the earth, וְהִשְׁקָה and watered (as it were, and ever watered afresh), &c. This frequentative use of the perfect consecutive is equally evident after frequentative imperfects, Gn 210 (וְהָיָה and it became again every time; וַיְהִי would mean, and it became so once for all); 29:2f. (four perfects consecutive referring to actions repeated daily); Ex 337–11 יִקַּח he used to take at each new encampment the tent, וְנָטָה and to pitch it again every time without the camp; notice, amongst the numerous frequent. perff. consec., the imperf. in vv. 7, 8, 9, 11, always in a frequentative sense; 34:34f., Nu 919, 21 (among several simple imperfects), 10:17, Ju 219, 1 S 219 תַּֽעֲשֶׂה
