It with the olive branch announced to Noah that "the rain was over and gone" (Ge 8:11). So John the Baptist, spiritually. Its plaintive "voice" answers to his preaching of repentance (Jr 8:6, 7). Vulgate and Septuagint translate, "The time of pruning," namely, spring (Joh 15:2). The mention of the "turtle's" cooing better accords with our text. The turtledove is migratory (Jr 8:7), and "comes" early in May; emblem of love, and so of the Holy Ghost. Love, too, shall be the keynote of the "new song" hereafter (Is 35:10; Re 1:5; 14:3; 19:6). In the individual believer now, joy and love are here set forth in their earlier manifestations (Mr 4:28).
