2 Timothy 2:19
However, the solid foundation of God stands firm. [Note: This probably refers to the church. See I Tim. 3:15].

[See Isa. 36:13].
Hebrews 12:23
and to the church of the firstborn ones [i.e., those who have received an inheritance from their Father], whose names are recorded in heaven. [See Luke 10:20].

These people are the ones who did not practice sexual immorality with women, for they were virgins [Note: This probably has reference to people who avoided idolatry]. These are people who followed the Lamb wherever He went. They were purchased from among mankind to be the firstfruits [devoted] to God and to the Lamb.
