orders, laws, command, decree, good
令 centers on authoritative directives: orders, commands, laws, and decrees. The meaning 'good' is a separate, less common sense that does not clearly connect to the directive idea.
令 is thought to depict a person kneeling under a roof or authority, representing a command or decree. The modern form retains the top element suggesting authority and the lower kneeling shape.
The top 亽 looks like a roof or a person giving orders, and the bottom 龴 resembles a kneeling figure receiving them. Together, 令 shows a command being issued.
For レイ, imagine a ruler named Ray issuing a decree: Ray -> レイ, and his orders are law.
