SEV Biblia, Chapter 6:10
Y les decía: Dondequiera que entréis en una casa, posad en ella hasta que salgáis de allí.
John Gill's Bible Commentary
Ver. 10. And he said unto them , etc..] He continued giving orders and directions to them, saying, in what place soever you enter into an house, there abide till ye depart from that place : that is, in whatsoever city or town they should come to, the first house they went into, they should continue in, during their stay in that city or town, and not shift from house to house; (see Gill on “ Matthew 10:11”).
Matthew Henry Commentary
Verses 7-13 - Though the apostles were conscious to themselves of great weakness, an expected no wordly advantage, yet, in obedience to their Master, and i dependence upon his strength, they went out. They did not amuse people with curious matters, but told them they must repent of their sins, an turn to God. The servants of Christ may hope to turn many from darknes unto God, and to heal souls by the power of the Holy Ghost.

Robertson's NT Word Studies
6:10 {There abide} (ekei menete). So also #Mt 10:11; Lu 9:4. Only Matthew has city or village (#10:11), but he mentions house in verse #12. They were to avoid a restless and dissatisfied manner and to take pains in choosing a home. It is not a prohibition against accepting invitations.
