XVIII, 16.');"><sup>8</sup></span> just as there, five sela's is meant , so here too five sela's is mea Then perhaps five sela's in all? - Were 'empty' written at the end [of the verse],<span class="x" onmousemove="('comment',' 'Thou shalt furnish . . thy wine-press; and thou shalt not let him go empty.');"><sup>9</sup></span> [it would be] as you say.
