Deuteronomy 6:13, Isaiah 65:16, and Jeremiah 4:2 and 12:16 all positively command swearing by Yahweh's name. Matthew 5:34-37 has Jesus saying "swear not at all" — no heaven, no earth, just yes-yes and no-no, and anything more "cometh of evil." Torah makes oaths by God's name an act of covenantal loyalty; Jesus makes them a moral problem.
Proposed answers
People have answered this in several ways; GEBible presents them as equal peers.
16so that he who blesses himself in the earth will bless himself in the God of truth; and he who swears in the earth will swear by the God of truth; because the former troubles are forgotten, and because they are hidden from my eyes.
2and you will swear, ‘As Yahweh lives,’ in truth, in justice, and in righteousness. The nations will bless themselves in him, and they will glory in him.”
16It will happen, if they will diligently learn the ways of my people, to swear by my name, ‘As Yahweh lives;’ even as they taught my people to swear by Baal, then they will be built up in the middle of my people.
34but I tell you, don’t swear at all: neither by heaven, for it is the throne of God;35nor by the earth, for it is the footstool of his feet; nor by Jerusalem, for it is the city of the great King.36Neither shall you swear by your head, for you can’t make one hair white or black.37But let your ‘Yes’ be ‘Yes’ and your ‘No’ be ‘No.’ Whatever is more than these is of the evil one.

How critical scholarship weighs this: Leans toward a genuine contradiction
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
The Hebrew Bible does not merely tolerate oaths in Yahweh's name; it commands them as acts of covenant fidelity. Deuteronomy 6:13 and 10:20 pair fearing God, serving him, and swearing by his name as a single triad of loyalty, deliberately contrasting Israelite oaths with oaths sworn by foreign gods. Isaiah 65:16 envisions a future in which people swear "by the God of truth" (*bēʾlōhê ʾāmēn*), and Jeremiah 4:2 and 12:16 make swearing "the LORD lives" (*ḥay-YHWH*) the mark of a converted, restored nation. To swear by Yahweh's name was to confess his exclusive lordship; in this stream of thought, refusing to swear by it could itself verge on apostasy, since the practical alternative was swearing by other gods.
Matthew 5:34-37 cuts against this. The Greek is emphatic: *egō de legō hymin mē omosai holōs* — "but I say to you, do not swear at all." *Holōs* ("at all," "wholly") is categorical, and the four prohibited oath-formulas (by heaven, by earth, by Jerusalem, by one's head) are followed by the demand that speech be simply "yes yes, no no," with anything beyond this *ek tou ponērou* — "from the evil one" or "of evil." James 5:12, almost certainly drawing on the same dominical tradition, repeats the prohibition with equal force: "above all, my brothers, do not swear" (*Pro pantōn de, adelphoi mou, mē omnyete*).
The standard harmonization, defended by D. A. Carson and Craig Blomberg, is that Jesus targets not oaths as such but the casuistic abuse of oaths in first-century Judaism, whereby swearing by lesser things (Jerusalem, one's head, the gold of the temple) created an escape hatch from binding obligation. Matthew 23:16-22 lends this real support: there Jesus explicitly attacks the graded system in which swearing by the temple counts for nothing but swearing by its gold binds. On this reading, Jesus demands a transparent truthfulness that makes oaths superfluous, not the abolition of the lawful Yahwistic oath. The argument is serious and is partially correct about the abuses being addressed.
It nonetheless strains against the categorical form of the saying and against the reception history. The Essenes, per Josephus (*Jewish War* 2.135), avoided oaths altogether and held that one who is not believed without invoking God stands already condemned; Sirach 23:9-11 warns against habituating the mouth to oaths. Jesus' formula stands in this stream of intensified piety and reads most naturally as an absolute. Significant strands of the early church took it so: Justin Martyr cites "swear not at all" as a binding command of Christ (1 Apology 16), and the Anabaptists and later the Quakers refused all oaths on the strength of these verses — and they were not misreading the plain sense. (The Didache, by contrast, should not be enlisted here: Did. 2.3 forbids false and perjured oaths, echoing the Decalogue, not all swearing.) Davies and Allison, in the ICC, locate the saying within the structure of Matthew's antitheses ("you have heard... but I say to you"), where Jesus characteristically intensifies or transcends a Torah provision — here a provision that not only permitted but commanded oaths. Ulrich Luz in Hermeneia likewise reads it as a radicalization rather than a mere clarification of abuse.
The distinction matters because the harmonization succeeds only by narrowing "swear not at all" to "swear not abusively." If one grants that Jesus is sharpening and partly overriding Torah under the inbreaking kingdom — the same move he makes on divorce (Matt 5:31-32) and retaliation (5:38-39), neither of which is a mere policing of misuse — then the relationship to Deuteronomy 6:13 is one of deliberate transcendence: not contradiction in the sense of a logical blunder by a single author, but genuine tension between two normative positions advanced by two traditions. What cannot be sustained is the claim that Deuteronomy's command to swear and Jesus' command not to swear say the same thing. Deuteronomy makes the oath a positive act of fidelity; Matthew makes it, at minimum, a concession to a fallen condition and, on its face, something to be renounced.
Where the critical reading lands: genuine tension, harmonizable only by conceding that Jesus revises the Torah's positive command rather than merely correcting its abuse.
