Link Isaiah 37:28 & Psalm 139:1-4?
How does God's knowledge in Isaiah 37:28 connect with Psalm 139:1-4?

Setting the Context

Isaiah 37 records God’s response to the boasting of Assyria’s king. In verse 28 He declares, “But I know your sitting down and your going out and your coming in and your raging against Me” (Isaiah 37:28).

Psalm 139 is David’s personal reflection on God’s intimate knowledge of His people. Verses 1-4 read:

“O LORD, You have searched me and known me.

You know when I sit and when I rise; You understand my thoughts from afar.

You search out my path and my lying down; You are aware of all my ways.

Even before a word is on my tongue, You know all about it, O LORD.”


God’s Omniscience on Display

• Both passages affirm that nothing escapes God’s attention—whether the schemes of an arrogant king or the most private movements of a devoted believer.

• The verbs “know,” “search,” and “understand” present God’s knowledge as exhaustive and active, not passive.

• The specific phrasing “sitting down,” “going out,” and “coming in” appears in both texts, emphasizing everyday, ordinary actions that God monitors with perfect clarity.


Connecting the Passages

Isaiah 37:28 applies God’s omniscience to a national enemy; Psalm 139:1-4 applies the same truth to an individual believer.

• This overlap shows that God’s knowledge is universal: it confronts the proud (Assyria) and comforts the humble (David).

• In both cases God’s knowledge leads to decisive action—judgment for Assyria (Isaiah 37:33-38) and guidance for David (Psalm 139:9-10, 23-24).


Implications for Us

• Security: If God tracks an invader’s every move, He certainly oversees the details of our lives (cf. Matthew 10:29-31).

• Accountability: Nothing is hidden; motives and words are laid bare before Him (Hebrews 4:13).

• Worship: The same God who disciplines nations invites personal intimacy with His children (Jeremiah 23:23-24).


Supporting Scriptures

2 Chronicles 16:9 — “For the eyes of the LORD roam to and fro over all the earth…”

Proverbs 5:21 — “For a man’s ways are before the eyes of the LORD, and He considers all his paths.”

John 2:24-25 — Jesus “knew all men” and “knew what was in a man.”


Takeaway Truths

• God’s knowledge is limitless, immediate, and personal.

• What terrifies the rebellious reassures the faithful.

• The identical language in Isaiah 37:28 and Psalm 139:1-4 anchors our confidence that the Lord knows, cares, and will act in perfect wisdom on behalf of His purposes and His people.
