even Solomon ... was not clothed like one of these

Jesus speaks about the lilies as if they were people who wore clothes. The lilies being clothed is a metaphor for the plants having beautiful and colorful flowers. (See: rc://en/ta/man/jit/figs-personification and rc://en/ta/man/jit/figs-metaphor)

I say to you

This adds emphasis to what Jesus says next.

was not clothed like one of these

This can be stated in active form. Alternate translation: "did not wear clothes that are as beautiful as these lilies" (See: rc://en/ta/man/jit/figs-activepassive)
