Final answer:
Israel should not swear an oath saying 'As the Lord lives,' as this would associate God's name with idol worship or false declarations, according to Hosea 4:15.
Step-by-step explanation:
According to Hosea 4:15, Israel should not swear an oath saying, “As the Lord lives”, pertaining to pledges or declarations invoking God's name falsely or in connection with idolatrous practices. The broader scriptural context prohibits idol worship and emphasizes faithfulness to the one God of Israel. This instruction is consonant with the commandment against making idols and the condemnation of false oaths in the Old Testament.
