This noun denotes inward meditation or reflective musing, appearing in a wisdom psalm. The psalmist promises that his mouth will speak wisdom, and the meditation of his heart will be understanding. The word emphasizes the internal mental process underlying wise speech—one does not simply blurt wisdom, but cultivates it through careful thought. The term comes from the same root as 'murmur' or 'mutter,' suggesting the quiet internal verbal process of meditation. Spanish 'meditación' and French 'méditation' perfectly capture this contemplative activity.
