A.T. Robertson Commentary Acts 5:8

"And Peter answered unto her, Tell me whether ye sold the land for so much. And she said, Yea, for so much." — Acts 5:8 (ASV)

For so much (τοσουτου). Genitive of price. Perhaps Peter pointed to the pile of money at the feet of the apostles (verse 2). The use of ε in direct questions appears in Luke (Luke 13:23; Luke 22:49) as in the LXX like the Hebrew im and in Ac 1:6; 19:2, etc.
