1 Timothy 4:13 instructs Timothy 'till I come' — directly continuing the thought of Paul's hoped-for visit in 3:14, telling Timothy what to do in the meantime.

2 John 1:12 expresses the same hope to come and speak face to face — a common epistolary formula that parallels Paul's desire in 1 Timothy 3:14.

3 John 1:14 echoes Paul's hope to visit soon and speak face to face — same personal epistolary closing.

2 Corinthians 1:15-17 shows Paul's travel plans could change — providing a real-life example that his stated hope to come (as in 1 Timothy 3:14) was sincere but not always realized.

1 Thessalonians 2:18 reveals Paul wanted to come but was hindered by Satan — another instance of his earnest desire to visit, like in 1 Timothy 3:14.

Philemon 1:22 has Paul asking for a guest room, trusting he will come — a practical outworking of the same hope to visit expressed in 1 Timothy 3:14.
