Boyd’s Bible Dictionary:

(written). By way of preeminence, the sacred writings contained in the Old and New Testaments. [BIBLE.]

Concise Bible Dictionary:

This word occurs but once in the Old Testament, where an angel speaks of “the scripture of truth” (Dan. 10:2121But I will show thee that which is noted in the scripture of truth: and there is none that holdeth with me in these things, but Michael your prince. (Daniel 10:21)). In the New Testament the various parts of the Old Testament are referred to as “the scriptures;” they are the “holy scriptures” (2 Tim. 3:1515And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. (2 Timothy 3:15)): they must needs be fulfilled; they cannot be broken (John 10:3535If he called them gods, unto whom the word of God came, and the scripture cannot be broken; (John 10:35); Acts 17:2, 112And Paul, as his manner was, went in unto them, and three sabbath days reasoned with them out of the scriptures, (Acts 17:2)
11These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so. (Acts 17:11)
). Some erred because they did not know the scriptures (Matt. 22:2929Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. (Matthew 22:29)). And “all scripture” is God-inspired, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness; that the man of God may be perfect, or complete, fully fitted to every good work (2 Tim. 3:16-1716All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 17That the man of God may be perfect, throughly furnished unto all good works. (2 Timothy 3:16‑17)). It is in short a God-inspired and infallible revelation to man, and especially to those who are by grace in relationship with Him. As in a nation “the records” are referred to as authority, so in the church, it is “the scriptures” that bind the conscience, and should be an end of all controversy. To understand them the teaching of the Holy Spirit is needed, for “the letter killeth, but the Spirit giveth life.”
