So when you give alms

"So when you give to poor people"

do not sound a trumpet before yourself

This means to do something that purposefully gets people's attention. Alternate translation: "do not draw attention to yourself like someone who plays a loud trumpet in a crowd"

Truly I say to you

"I tell you the truth." This phrase adds emphasis to what Jesus says next.
