Genesis 26:15 סִתְּמ֣וּם they stopped up them

So the Philistines took dirt and stopped up all the wells that his father’s servants had dug in the days of his father Abraham.

Here: "(They) stopped them up." The verb form expresses complete, effective blocking, and the attached "them" points back to "all the wells." Elsewhere in the Bible the same action is a war tactic for denying an enemy water (2 Kgs 3:19, 25; 2 Chr 32:3–4).

Genesis 26:18 וַיְסַתְּמ֣וּם and they had stopped up them

Isaac reopened the wells that had been dug in the days of his father Abraham, which the Philistines had stopped up after Abraham died. And he gave these wells the same names his father had given them.

2 Kings 3:25 יִסְתֹּ֙מוּ֙ they stopped up

They destroyed the cities, and each man threw stones on every good field until it was covered. They stopped up every spring and cut down every good tree. Only Kir-haraseth was left with stones in place, but men with slings surrounded it and attacked it as well.

Nehemiah 4:7 לְהִסָּתֵ֑ם to be closed

When Sanballat and Tobiah, together with the Arabs, Ammonites, and Ashdodites, heard that the repair to the walls of Jerusalem was progressing and that the gaps were being closed, they were furious,

Here: "To be stopped up," a verb used for blocking or plugging something, like filling in a well. The open city was being sealed.

Psalm 51:6 וּ֝בְסָתֻ֗ם and in a [place] kept secret

Surely You desire truth in the inmost being; You teach me wisdom in the inmost place.

Here: 'And in the shut-up (place).' A form meaning 'closed off, sealed', used of wells that were stopped up and of words kept sealed. It matches 'covered-over places': the closed-off interior that no one else can see.

Lamentations 3:8 שָׂתַ֖ם he has shut out

Even when I cry out and plead for help, He shuts out my prayer.

Here: 'He has stopped up.' The picture is plugging something closed, as wells were stopped up with earth (Gen 26:15, 18). The perfect form presents the blockage as already done and in place before he even cries.

Ezekiel 28:3 סָת֖וּם secret [thing]

Behold, you are wiser than Daniel; no secret is hidden from you!

Here: A form meaning 'something that has been stopped up or sealed'. The verb is used of wells blocked with earth and of a vision 'sealed up' until the end. Here it means a closed-off mystery, hidden knowledge.

Daniel 8:26 סְתֹ֣ם keep secret

The vision of the evenings and the mornings that has been spoken is true. Now you must seal up the vision, for it concerns the distant future.”

Here: A command. The verb is used for stopping up wells and springs. Here it means keep the vision closed: guard it, and do not make it public or open it to use yet.

Daniel 12:4 סְתֹ֧ם keep secret

But you, Daniel, shut up these words and seal the book until the time of the end. Many will roam to and fro, and knowledge will increase.”

Here: A command: 'close up / keep hidden.' The same verb is used for stopping up wells (Gen 26:15). Here it means keeping the revelation closed and stored away until its time, not destroying it.

Daniel 12:9 סְתֻמִ֧ים [are] kept secret

“Go on your way, Daniel,” he replied, “for the words are closed up and sealed until the time of the end.

Here: A passive form describing a state: the words *are* closed. Elsewhere the verb is used for stopping up wells and closing gaps in a wall. Here it means the meaning is shut away and not open to Daniel. It comes first in the clause for emphasis.
