Ephesians 1:3-14 EMTV
(3) Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenlies in Christ, (4) just as He chose us in Him before the foundation of the world, that we should be holy and blameless before Him in love, (5) having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will, (6) to the praise of the glory of His grace, by which He bestowed favor upon us in the Beloved.
2 Thessalonians 2:13-14 LITV
(13) But we ought to thank God always concerning you, brothers, beloved by the Lord, because God chose you from the beginning to salvation in sanctification of the Spirit and belief of the truth, (14) to which He called you through our gospel, to obtain the glory of our Lord Jesus Christ.
The Lord does not delay concerning His promise, as some reckon slackness, but is longsuffering toward us, not willing that any should perish, but that all should come to repentance. (2 Peter 3:9 EMTV)
The pictures above illustrate the etymology of the word used for foundation of the earth or the word both in Hebrews and in Greek. The Greek word our translations use to convey the idea of foundation of the word is not close to the idea of the Hebrew tongue and its Greek counterpart in the Septuagint. The New Testament does use the proper Greek equivalent for foundation in comparison to the Hebrew. "Katabole", the word translated in the "foundation of the world", is the word used for Sarah, the wife of Abraham, to describe that God enabled her to conceive at an old age.

Foundation of the earth reference in the Scriptures
Predestination, from the perspective of salvation, is the belief that God already knew and chose who, born and unborn, will be saved, and, therefore, there is nothing an individual can do for or against his destiny.
Throw that doctrine of predestination at the verses quoted here and judge how the doctrine stands to biblical scrutiny. Meditate on the doctrine and ask yourself if there would any sense for the redemptive sacrifice of Jesus, assuming that, by predestination, the fate of every individual had already been sealed.
