Husband /ˈhəzbənd/ comes from house, because it comes from the old Nordic húsbóndi, composed of hús (house) + bóandi (inhabitant, dweller).

That is, the one that exists or that inhabits a house, also probably related to bind, meaning one who consolidates the union of the family with his presence and work.

Consequently, this word is also linked to the idea of agriculture, since in the middle ages labor consisted predominantly of planting and rearing animals, and the distinction between ‘dwelling-place’ and ‘farmer’ was not very clear.

This can be observed in the word husbandry (the care, cultivation, and breeding of crops and animals).
