The flowers appear on the earth; the time of the singing of birds is come, and the voice of the turtle is heard in our land;

Wesley's Notes

2:12 The flowers - The communications of God's grace, the gifts, and graces, and comforts of the Holy Spirit, are vouchsafed unto, and appear in believers, as buds and blossoms do in the spring. The turtle - This seems particularly to be mentioned because it not only gives notice of the spring, but aptly represents the Spirit of God, which even the Chaldee paraphrast understands by this turtle, which appeared in the shape of a dove, and which worketh a dove - like meekness, and chastity, and faithfulness, in believers.

Jamieson-Fausset-Brown Bible Commentary

12. flowers-tokens of anger past, and of grace come. "The summoned bride is welcome," say some fathers, "to weave from them garlands of beauty, wherewith she may adorn herself to meet the King." Historically, the flowers, &c., only give promise; the fruit is not ripe yet; suitable to the preaching of John the Baptist, "The kingdom of heaven is at hand"; not yet fully come.

the time of . singing-the rejoicing at the advent of Jesus Christ. Gregory Nyssenus refers the voice of the turtledove to John the Baptist. 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 (Jer 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 (Jer 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 (Isa 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).

Matthew Henry's Concise Commentary

2:8-13 The church pleases herself with thoughts of further communion with Christ. None besides can speak to the heart. She sees him come. This may be applied to the prospect the Old Testament saints had of Christ's coming in the flesh. He comes as pleased with his own undertaking. He comes speedily. Even when Christ seems to forsake, it is but for a moment; he will soon return with everlasting loving-kindness. The saints of old saw him, appearing through the sacrifices and ceremonial institutions. We see him through a glass darkly, as he manifests himself through the lattices. Christ invites the new convert to arise from sloth and despondency, and to leave sin and worldly vanities, for union and communion with him. The winter may mean years passed in ignorance and sin, unfruitful and miserable, or storms and tempests that accompanied his conviction of guilt and danger. Even the unripe fruits of holiness are pleasant unto Him whose grace has produced them. All these encouraging tokens and evidences of Divine favour, are motives to the soul to follow Christ more fully. Arise then, and come away from the world and the flesh, come into fellowship with Christ. This blessed change is owing wholly to the approaches and influences of the Sun of righteousness.
