'Declines' in the Bible

And on the fifth day he arose early in the morning to depart; and the girl's father said, "Strengthen your heart, and tarry until the day declines." So they ate, both of them.

My days are like an evening shadow that lengthens and vanishes [with the sun];And as for me, I wither away like grass.

I am vanishing like a shadow when it lengthens and fades;I am shaken off like the locust.

“Prepare war against her;Arise, and let us attack at noon.Woe to us, for the day declines,For the shadows of the evening lengthen!
