1 Korintus 9:11

9:11 If we sowed spiritual blessings among you, is it too much to reap material things from you?

1 Korintus 14:4

14:4 The one who speaks in a tongue builds himself up, ¹  but the one who prophesies builds up the church.

[14:4]  ¹ sn The Greek term builds (himself) up does not necessarily bear positive connotations in this context.
