'Willows' in the Bible

And ye shall take you on the first day the boughs of goodly trees, branches of palm trees, and the boughs of thick trees, and willows of the brook; and ye shall rejoice before the LORD your God seven days.

The shady trees cover him with their shadow; the willows of the brook compass him about.

We hanged our harps upon the willows in the midst thereof.

Therefore the abundance they have gotten, and that which they have laid up, shall they carry away to the brook of the willows.

And they shall spring up as among the grass, as willows by the water courses.
