Exodus 30:37Meaning & Commentary from the Church Fathers

It is prohibited for anyone to engage in acts solely for personal pleasure, meaning one should not claim credit for oneself, but rather direct all glory to God, the source of all goodness. Isaiah 1:3

The offerings of peace and incense, established by divine order, were not only unsuitable for everyday use, but their specific formulation was strictly prohibited from being duplicated at will. They were reserved exclusively for the worship of the Lord.
