Additional Hebrew terms that convey the idea of investigation found in the New International Dictionary of Old Testament Theology & Exegesis (Grand Rapids, MI: Zondervan, 1997) have been included. I am putting them all together here in one place, showing the term’s transliterated forms. Those familiar with Hebrew will note that these are given (for the most part) in a simplified form of transliteration, together with numbers for those using Strong’s system. The Greek terms are also given in a simplified form with Strong's numbers.

The object of giving this list of foundational passage is that it gives a sense of how pervasive and important the doctrine of testing, trying, searching, examining, and investigating believers is in the Bible.

Note on the passages from the book of Job: In Job 7:18 we see Job wondering why God would bother to test him. In Job 10:5-6 Job seems to have a hard time accepting the idea that God inquires (1245, baqash) as to his iniquity, searches (1875, darash) for his sin: "Are thy days as the days of man? are thy years as man's days, That thou inquirest after mine iniquity, and searchest after my sin?" Actually, Job is to a certain degree right in his skepticism. In the context of his present situation it is really Satan that is testing him every moment, inquiring after Job's iniquity, and searching for sin in him. Yet, the point remains that God does take advantage of, if He does not cause, our troubles to make sin obvious to us. Therefore, Job is distressed and wondering why, but not denying, that God tests man. Later, Job comes to accept the idea that he is being tested and examined; for, he says, "When He works on the left hand, I cannot behold Him; when He turns to the right hand, I cannot see Him. But He knows the way that I take; when He has tested me, Ishall come forth as gold. My foot has held fast to His steps; I have kept His way and not turned aside. I have not departed from the commandment of His lips; I have treasured the words of His mouth more than my necessary food (Job 23:9-12 NKJ)." Job also indicates that others are examined in Job 13:9: "Will it be well when He searches you out?"

An Expanded List of Bible Passages that form the Doctrine of Believer Testing and Investigation
No great truth of Scripture is proven with a single text. The great fundamental Bible doctrines (for example, as the mercy of God and the second coming) are proven by numerous clear biblical statements. It is found that each scriptural statement refines, clarifies, and defines what God seeks to reveal. It is as if each passage is as a fence post that falls in line with and supports a line of truth that threads its way over the landscape of biblical themes. Thus the essential truths of God’s Word are usually found to be repeated in different terms and contexts from the beginning to the end of the Bible. Such is the case with the foundational passages for the doctrine of believer investigation.

The doctrines of believer probation and the investigative judgment are part of the Bible’s doctrine of believer testing. The following passages make use of Hebrew and Greek terms that, in their context, convey the idea of God’s investigation, searching, examining, and purifying of believers. Most of these passages are found in Chapters 2 and 7.
