The Song of Songs 2:12

2:12 The pomegranates have appeared in the land,

the time for pruning and singing has come;

the voice of the turtledove is heard in our land.

Jeremiah 8:7

8:7 Even the stork knows

when it is time to move on.

The turtledove, swallow, and crane

recognize the normal times for their migration.

But my people pay no attention

to what I, the Lord, require of them.
