Note held in the hand of a man in a portrait from 1580

This is an unusual request on the Forum, and I realise it's a difficult task but would welcome even a small suggestion as to what the text says- if indeed it is readable at all.

The note is held in the hand of Adriaen de Vriese who lived in Harlaam. The portrait is dated 1580 when he was 32 yrs old. He was the great grandfather of the Schoonhoven sisters who I'm researching.

with many thanks as always.

p.s I'll add a second photo of the note- taken without illumination in case that's 'easier' to read....
