Acts 16:33

‘And he took them the same hour of the night, and washed their stripes, and was baptised, he and all his, immediately.'

Meanwhile the jailer had taken them immediately from the prison and washed their wounds. He was a changed man. We are probably to see that he did the washing himself. Unbeknown to him he was following in the footsteps of a Greater than he (John 13:1). This would presumably be done at a well in the courtyard of the house, and having heard more of ‘the word' he and all his family and servants were baptised. ‘Immediately' means that there was no delay. It does not mean that they were not instructed first.
