Seed time and harvest 

Genesis 8:22

While the earth remains, seedtime and harvest, cold and heat, summer and winter,

 day and night, shall not cease.

Matthew 13:23

As for what was sown on good soil,

this is the one who hears the word and understands it.

He indeed bears fruit and yields,

 in one case a hundredfold,

in another sixty, and in another thirty.
