Psalms 101:6

Mine eyes shall be upon the faithful of the land ... - I will look to them to be employed in my house, and in my service. The word rendered “faithful” means those who are worthy of belief or confidence. It does not “necessarily” mean those who are pious or religious - though it is often used to denote such persons, in reference to the principal trait in the character of the pious, that is, confidence or faith in God. The essential meaning here is, that he would seek those who were trustworthy; on whom he could place reliance; whose truth, fidelity, and honesty he could confide in. This would be most certainly found in those who are “faithful” to God, and who would then be “faithful” to lower obligations. Undoubtedly, also, it is desirable, on some accounts, to have only such in our employ, if such can be found. But we are not to regard this passage as teaching the doctrine, even by the example of the psalmist, that we are to employ no persons but such as are truly religious. There are others who will be found faithful, honest, and reliable; and they have such a claim to our confidence as to impose on us a moral obligation to show them that confidence - so far, at least, that we shall not, by any act of ours, declare them not worthy of trust because they are not religious. Besides, it may be desirable, on many accounts, that persons who are not religious should be brought under the influence of religion in pious families, and enjoy the advantages which may be connected with a religious household. In seeking our own interest, and what will be for our own welfare and happiness, we should not be unmindful of what may be for the good of others. Religion may extend itself much in the world by thus bringing into the service of religious households those who may, by example, instruction, and prayer, be led to the possession and practice of true religion.

He that walketh in a perfect way ... - Margin, “perfect in the way.” The translation in the text is the more correct. The phrase means an upright man; a man of integrity. It does not necessarily imply that he is absolutely holy, or free from all sin, but that he is upright, consistent, honest: a man whose moral character is developed in proper proportions, or is such that it may be relied on. See the notes at Job 1:1.
