Treasury of Scripture Knowledge
And then I will declare to them, 'I never acknowledged you [as my people]; go away from me, you people who have done sinful things.'
I am the good shepherd and I know my sheep [intimately], and they know me [that way],
Then Jesus asked him a third time, "Simon, son of John, do you [truly] love me?" Peter was sad because Jesus had asked him a third time, "Do you [even] love me?" So, he said to Jesus, "Lord, you know all things. You [surely] know that I love you." Jesus replied to him, "[Then] feed my sheep.
For [that class of] persons whom God knew beforehand He also predetermined to become conformed to the [spiritual] likeness of His Son, so that He could be the firstborn One among [His] many brothers [i.e., so He could be the preeminent example to all His followers. See Heb. 2:11].
God did not reject His people whom He knew previously. Or, do you not know what the Scriptures say in the passage where Elijah pleads with God against Israel?
But now that you have come to know God [as your Father], or rather, to be known by Him [as His children], how can you turn back again to the weak, cheap, elementary teachings [of the law of Moses], to which you [seem to] desire to become enslaved?
2 Timothy 2:19
However, the solid foundation of God stands firm. [Note: This probably refers to the church. See I Tim. 3:15]. It is sealed with these words [i.e., certifying God's ownership and a commitment to Him]: "The Lord knows those who are His people," [See Num. 16:5], and "Everyone who confesses the name of the Lord should stop practicing wickedness." [See Isa. 36:13].
I know [about] your suffering and your poverty (but you are [really] rich), and the slander of those who say they are Jews, though they [really] are not, but are a synagogue of Satan [i.e., they claimed to be an assembly of God's people, but in reality were serving Satan].
I know about your deeds. (See, I have placed before you an open door, which no one can close). [Note: This probably refers to their being assured of some unspecified opportunity]. [I know] that you have [only] a little bit of strength, but [in spite of that] you have obeyed my word and did not deny my name.
