Metta meditation ever taught to householders?

Are there references that the Buddha taught such as metta-meditation to householders (wordlings, without complete Sila), giving ground for hypocritical practice, agree with such, in manners of: "There is the case where a householder..."? Didn't he not focused on getting right view and Silas first? Was modern householder-metta-meditation ever taught, even trained by the elders, such as doing it inbetween business as usual? *[Note: this is not given for trade, exchange, stacks and to maintain houses but for liberation and with non-hypocratical metta: may all beings give causes to find there way out for themselves with ease.]*
