'Rivulets' in the Bible

And he hath been as a tree, Planted by rivulets of water, That giveth its fruit in its season, And its leaf doth not wither, And all that he doth he causeth to prosper.

A river -- its rivulets rejoice the city of God, Thy holy place of the tabernacles of the Most High.

Rivulets of waters have come down mine eyes, Because they have not kept Thy law!
