Song of Solomon 7:2 (ESV)

2 Your navel is a rounded bowl that never lacks mixed wine. Your belly is a heap of wheat, encircled with lilies.

The man’s love even makes him marvel at his wife’s navel. His wife is so beautiful in his eyes. Even her navel is a feast for him. It makes him think of a festive glass of wine.

He also admires the tint of her belly. Its hue reminds him of the colour of wheat lying in a heap. He underscores the beauty of it by an image of lilies surrounding that pile of wheat.
