watchmen

men who have the job of keeping guard of the town at night to keep the people safe

as they were making their rounds in the city

"who were walking around the city on the walls"

him whom my soul loves

The soul is a metonym for the whole person. Here it makes a stronger statement of the woman's love for the man than "my beloved" (Song of Songs 1:14). See how you translated this in Song of Songs 3:1. (See: rc://en/ta/man/jit/figs-metonymy)
