What does Daniel 5:14 mean?

Belshazzar claims to have heard about Daniel's skills, though he may be merely repeating what the queen had just told him (Daniel 5:10–12). Despite worshipping idols and blaspheming sacred objects (Exodus 30:22–29; Daniel 1:1–2) taken from Israel (Daniel 5:1–4), Belshazzar made a point of referring to Daniel using his Hebrew name (Daniel 5:13). It's possible he suspected that his actions angered the God of Israel, triggering the supernatural sight of a hand writing on the wall (Daniel 5:5). This seems to have terrified the king enough that he will do anything to know what the words mean (Daniel 5:6–9). On the queen's urging he had summoned Daniel.

Babylon's so-called wise men had failed to interpret the text. In fact, they could not even read it—suggesting it was in some other language, code, or cipher. Yet Daniel had access to wisdom far superior to theirs (Daniel 1:17; 2:30). Knowledge of God and relationship with His Spirit are necessary to fully understand His will (Colossians 2:2–3; 1 Corinthians 2:14).
